Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484630, here are decompositions:

3 + 31484627 = 31484630
13 + 31484617 = 31484630
61 + 31484569 = 31484630
97 + 31484533 = 31484630
127 + 31484503 = 31484630
181 + 31484449 = 31484630
271 + 31484359 = 31484630
277 + 31484353 = 31484630

Showing the first eight; more decompositions exist.
