Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484894, here are decompositions:

31 + 31484863 = 31484894
73 + 31484821 = 31484894
97 + 31484797 = 31484894
277 + 31484617 = 31484894
433 + 31484461 = 31484894
541 + 31484353 = 31484894
577 + 31484317 = 31484894
613 + 31484281 = 31484894

Showing the first eight; more decompositions exist.
