Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494256, here are decompositions:

113 + 31494143 = 31494256
137 + 31494119 = 31494256
173 + 31494083 = 31494256
257 + 31493999 = 31494256
347 + 31493909 = 31494256
467 + 31493789 = 31494256
683 + 31493573 = 31494256
743 + 31493513 = 31494256

Showing the first eight; more decompositions exist.
