Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490870, here are decompositions:

37 + 2147490833 = 2147490870
59 + 2147490811 = 2147490870
71 + 2147490799 = 2147490870
73 + 2147490797 = 2147490870
97 + 2147490773 = 2147490870
101 + 2147490769 = 2147490870
131 + 2147490739 = 2147490870
139 + 2147490731 = 2147490870

Showing the first eight; more decompositions exist.

IPv4 address
