Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443026, here are decompositions:

  • 5 + 2147443021 = 2147443026
  • 13 + 2147443013 = 2147443026
  • 23 + 2147443003 = 2147443026
  • 37 + 2147442989 = 2147443026
  • 199 + 2147442827 = 2147443026
  • 229 + 2147442797 = 2147443026
  • 263 + 2147442763 = 2147443026
  • 349 + 2147442677 = 2147443026

Showing the first eight; more decompositions exist.
