Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489790, here are decompositions:

73 + 2147489717 = 2147489790
137 + 2147489653 = 2147489790
139 + 2147489651 = 2147489790
151 + 2147489639 = 2147489790
211 + 2147489579 = 2147489790
307 + 2147489483 = 2147489790
317 + 2147489473 = 2147489790
349 + 2147489441 = 2147489790

Showing the first eight; more decompositions exist.

IPv4 address
