Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485892, here are decompositions:

3 + 2147485889 = 2147485892
31 + 2147485861 = 2147485892
73 + 2147485819 = 2147485892
523 + 2147485369 = 2147485892
631 + 2147485261 = 2147485892
691 + 2147485201 = 2147485892
751 + 2147485141 = 2147485892
1171 + 2147484721 = 2147485892

Showing the first eight; more decompositions exist.

IPv4 address
