Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484634, here are decompositions:

7 + 31484627 = 31484634
17 + 31484617 = 31484634
101 + 31484533 = 31484634
131 + 31484503 = 31484634
173 + 31484461 = 31484634
257 + 31484377 = 31484634
271 + 31484363 = 31484634
281 + 31484353 = 31484634

Showing the first eight; more decompositions exist.
