Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538060, here are decompositions:

  • 7 + 31538053 = 31538060
  • 13 + 31538047 = 31538060
  • 31 + 31538029 = 31538060
  • 61 + 31537999 = 31538060
  • 79 + 31537981 = 31538060
  • 139 + 31537921 = 31538060
  • 157 + 31537903 = 31538060
  • 199 + 31537861 = 31538060

Showing the first eight; more decompositions exist.
