Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545282, here are decompositions:

  • 61 + 31545221 = 31545282
  • 71 + 31545211 = 31545282
  • 101 + 31545181 = 31545282
  • 163 + 31545119 = 31545282
  • 191 + 31545091 = 31545282
  • 199 + 31545083 = 31545282
  • 233 + 31545049 = 31545282
  • 281 + 31545001 = 31545282

Showing the first eight; more decompositions exist.
