Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514190, here are decompositions:

  • 31 + 31514159 = 31514190
  • 41 + 31514149 = 31514190
  • 47 + 31514143 = 31514190
  • 89 + 31514101 = 31514190
  • 109 + 31514081 = 31514190
  • 131 + 31514059 = 31514190
  • 167 + 31514023 = 31514190
  • 223 + 31513967 = 31514190

Showing the first eight; more decompositions exist.
