Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463224, here are decompositions:

11 + 31463213 = 31463224
101 + 31463123 = 31463224
137 + 31463087 = 31463224
293 + 31462931 = 31463224
347 + 31462877 = 31463224
431 + 31462793 = 31463224
467 + 31462757 = 31463224
641 + 31462583 = 31463224

Showing the first eight; more decompositions exist.
