Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484936, here are decompositions:

73 + 31484863 = 31484936
97 + 31484839 = 31484936
139 + 31484797 = 31484936
367 + 31484569 = 31484936
433 + 31484503 = 31484936
487 + 31484449 = 31484936
523 + 31484413 = 31484936
577 + 31484359 = 31484936

Showing the first eight; more decompositions exist.
