Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476190, here are decompositions:

  • 3 + 31476187 = 31476190
  • 41 + 31476149 = 31476190
  • 47 + 31476143 = 31476190
  • 71 + 31476119 = 31476190
  • 131 + 31476059 = 31476190
  • 173 + 31476017 = 31476190
  • 227 + 31475963 = 31476190
  • 281 + 31475909 = 31476190

Showing the first eight; more decompositions exist.
