Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530624, here are decompositions:

7 + 31530617 = 31530624
17 + 31530607 = 31530624
31 + 31530593 = 31530624
53 + 31530571 = 31530624
101 + 31530523 = 31530624
127 + 31530497 = 31530624
137 + 31530487 = 31530624
173 + 31530451 = 31530624

Showing the first eight; more decompositions exist.

IPv4 address
