Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484502, here are decompositions:

41 + 31484461 = 31484502
53 + 31484449 = 31484502
89 + 31484413 = 31484502
139 + 31484363 = 31484502
149 + 31484353 = 31484502
163 + 31484339 = 31484502
199 + 31484303 = 31484502
263 + 31484239 = 31484502

Showing the first eight; more decompositions exist.
