Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484702, here are decompositions:

3 + 31484699 = 31484702
199 + 31484503 = 31484702
241 + 31484461 = 31484702
349 + 31484353 = 31484702
421 + 31484281 = 31484702
463 + 31484239 = 31484702
499 + 31484203 = 31484702
523 + 31484179 = 31484702

Showing the first eight; more decompositions exist.
