Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474496, here are decompositions:

7 + 31474489 = 31474496
73 + 31474423 = 31474496
139 + 31474357 = 31474496
283 + 31474213 = 31474496
367 + 31474129 = 31474496
439 + 31474057 = 31474496
463 + 31474033 = 31474496
967 + 31473529 = 31474496

Showing the first eight; more decompositions exist.
