Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528158, here are decompositions:

  • 7 + 31528151 = 31528158
  • 31 + 31528127 = 31528158
  • 37 + 31528121 = 31528158
  • 47 + 31528111 = 31528158
  • 89 + 31528069 = 31528158
  • 139 + 31528019 = 31528158
  • 157 + 31528001 = 31528158
  • 191 + 31527967 = 31528158

Showing the first eight; more decompositions exist.
