Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491578, here are decompositions:

5 + 2147491573 = 2147491578
19 + 2147491559 = 2147491578
31 + 2147491547 = 2147491578
41 + 2147491537 = 2147491578
61 + 2147491517 = 2147491578
101 + 2147491477 = 2147491578
229 + 2147491349 = 2147491578
317 + 2147491261 = 2147491578

Showing the first eight; more decompositions exist.

IPv4 address
