Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620524, here are decompositions:

  • 3 + 31620521 = 31620524
  • 7 + 31620517 = 31620524
  • 37 + 31620487 = 31620524
  • 43 + 31620481 = 31620524
  • 127 + 31620397 = 31620524
  • 181 + 31620343 = 31620524
  • 223 + 31620301 = 31620524
  • 373 + 31620151 = 31620524

Showing the first eight; more decompositions exist.
