Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463308, here are decompositions:

47 + 31463261 = 31463308
59 + 31463249 = 31463308
419 + 31462889 = 31463308
431 + 31462877 = 31463308
557 + 31462751 = 31463308
659 + 31462649 = 31463308
719 + 31462589 = 31463308
761 + 31462547 = 31463308

Showing the first eight; more decompositions exist.
