Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484480, here are decompositions:

19 + 31484461 = 31484480
31 + 31484449 = 31484480
67 + 31484413 = 31484480
103 + 31484377 = 31484480
127 + 31484353 = 31484480
163 + 31484317 = 31484480
199 + 31484281 = 31484480
241 + 31484239 = 31484480

Showing the first eight; more decompositions exist.
