Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72618, here are decompositions:

  • 5 + 72613 = 72618
  • 41 + 72577 = 72618
  • 59 + 72559 = 72618
  • 67 + 72551 = 72618
  • 71 + 72547 = 72618
  • 137 + 72481 = 72618
  • 149 + 72469 = 72618
  • 151 + 72467 = 72618

Showing the first eight; more decompositions exist.
