Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489786, here are decompositions:

73 + 2147489713 = 2147489786
199 + 2147489587 = 2147489786
283 + 2147489503 = 2147489786
313 + 2147489473 = 2147489786
349 + 2147489437 = 2147489786
439 + 2147489347 = 2147489786
487 + 2147489299 = 2147489786
523 + 2147489263 = 2147489786

Showing the first eight; more decompositions exist.

IPv4 address
