Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451464, here are decompositions:

3 + 31451461 = 31451464
167 + 31451297 = 31451464
263 + 31451201 = 31451464
293 + 31451171 = 31451464
353 + 31451111 = 31451464
431 + 31451033 = 31451464
467 + 31450997 = 31451464
503 + 31450961 = 31451464

Showing the first eight; more decompositions exist.
