Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489244, here are decompositions:

37 + 2147489207 = 2147489244
41 + 2147489203 = 2147489244
101 + 2147489143 = 2147489244
157 + 2147489087 = 2147489244
167 + 2147489077 = 2147489244
227 + 2147489017 = 2147489244
331 + 2147488913 = 2147489244
337 + 2147488907 = 2147489244

Showing the first eight; more decompositions exist.

IPv4 address
