Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484586, here are decompositions:

17 + 31484569 = 31484586
43 + 31484543 = 31484586
53 + 31484533 = 31484586
73 + 31484513 = 31484586
83 + 31484503 = 31484586
137 + 31484449 = 31484586
173 + 31484413 = 31484586
223 + 31484363 = 31484586

Showing the first eight; more decompositions exist.
