Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484600, here are decompositions:

31 + 31484569 = 31484600
67 + 31484533 = 31484600
97 + 31484503 = 31484600
139 + 31484461 = 31484600
151 + 31484449 = 31484600
223 + 31484377 = 31484600
241 + 31484359 = 31484600
283 + 31484317 = 31484600

Showing the first eight; more decompositions exist.
