Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502088, here are decompositions:

  • 5 + 31502083 = 31502088
  • 109 + 31501979 = 31502088
  • 131 + 31501957 = 31502088
  • 151 + 31501937 = 31502088
  • 181 + 31501907 = 31502088
  • 227 + 31501861 = 31502088
  • 239 + 31501849 = 31502088
  • 257 + 31501831 = 31502088

Showing the first eight; more decompositions exist.
