Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443118, here are decompositions:

  • 31 + 2147443087 = 2147443118
  • 61 + 2147443057 = 2147443118
  • 97 + 2147443021 = 2147443118
  • 157 + 2147442961 = 2147443118
  • 307 + 2147442811 = 2147443118
  • 367 + 2147442751 = 2147443118
  • 421 + 2147442697 = 2147443118
  • 607 + 2147442511 = 2147443118

Showing the first eight; more decompositions exist.
