Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494760, here are decompositions:

23 + 31494737 = 31494760
47 + 31494713 = 31494760
53 + 31494707 = 31494760
71 + 31494689 = 31494760
149 + 31494611 = 31494760
179 + 31494581 = 31494760
251 + 31494509 = 31494760
257 + 31494503 = 31494760

Showing the first eight; more decompositions exist.
