Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482764, here are decompositions:

3 + 31482761 = 31482764
97 + 31482667 = 31482764
151 + 31482613 = 31482764
337 + 31482427 = 31482764
421 + 31482343 = 31482764
457 + 31482307 = 31482764
487 + 31482277 = 31482764
661 + 31482103 = 31482764

Showing the first eight; more decompositions exist.
