Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490746, here are decompositions:

7 + 2147490739 = 2147490746
19 + 2147490727 = 2147490746
157 + 2147490589 = 2147490746
283 + 2147490463 = 2147490746
463 + 2147490283 = 2147490746
829 + 2147489917 = 2147490746
1033 + 2147489713 = 2147490746
1093 + 2147489653 = 2147490746

Showing the first eight; more decompositions exist.

IPv4 address
