Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506182, here are decompositions:

  • 79 + 31506103 = 31506182
  • 151 + 31506031 = 31506182
  • 193 + 31505989 = 31506182
  • 199 + 31505983 = 31506182
  • 223 + 31505959 = 31506182
  • 373 + 31505809 = 31506182
  • 523 + 31505659 = 31506182
  • 613 + 31505569 = 31506182

Showing the first eight; more decompositions exist.
