Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484570, here are decompositions:

37 + 31484533 = 31484570
67 + 31484503 = 31484570
109 + 31484461 = 31484570
157 + 31484413 = 31484570
193 + 31484377 = 31484570
211 + 31484359 = 31484570
331 + 31484239 = 31484570
367 + 31484203 = 31484570

Showing the first eight; more decompositions exist.
