Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484918, here are decompositions:

7 + 31484911 = 31484918
79 + 31484839 = 31484918
97 + 31484821 = 31484918
271 + 31484647 = 31484918
349 + 31484569 = 31484918
457 + 31484461 = 31484918
541 + 31484377 = 31484918
601 + 31484317 = 31484918

Showing the first eight; more decompositions exist.
