Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463806, here are decompositions:

47 + 31463759 = 31463806
89 + 31463717 = 31463806
317 + 31463489 = 31463806
347 + 31463459 = 31463806
419 + 31463387 = 31463806
443 + 31463363 = 31463806
557 + 31463249 = 31463806
593 + 31463213 = 31463806

Showing the first eight; more decompositions exist.
