Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443112, here are decompositions:

  • 79 + 2147443033 = 2147443112
  • 109 + 2147443003 = 2147443112
  • 151 + 2147442961 = 2147443112
  • 181 + 2147442931 = 2147443112
  • 211 + 2147442901 = 2147443112
  • 349 + 2147442763 = 2147443112
  • 439 + 2147442673 = 2147443112
  • 499 + 2147442613 = 2147443112

Showing the first eight; more decompositions exist.
