Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537814, here are decompositions:

67 + 31537747 = 31537814
73 + 31537741 = 31537814
97 + 31537717 = 31537814
127 + 31537687 = 31537814
211 + 31537603 = 31537814
223 + 31537591 = 31537814
241 + 31537573 = 31537814
271 + 31537543 = 31537814

Showing the first eight; more decompositions exist.

IPv4 address
