Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494964, here are decompositions:

41 + 31494923 = 31494964
197 + 31494767 = 31494964
227 + 31494737 = 31494964
251 + 31494713 = 31494964
257 + 31494707 = 31494964
353 + 31494611 = 31494964
383 + 31494581 = 31494964
461 + 31494503 = 31494964

Showing the first eight; more decompositions exist.
