Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491454, here are decompositions:

37 + 2147491417 = 2147491454
181 + 2147491273 = 2147491454
193 + 2147491261 = 2147491454
331 + 2147491123 = 2147491454
373 + 2147491081 = 2147491454
421 + 2147491033 = 2147491454
457 + 2147490997 = 2147491454
487 + 2147490967 = 2147491454

Showing the first eight; more decompositions exist.

IPv4 address
