Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465318, here are decompositions:

29 + 31465289 = 31465318
257 + 31465061 = 31465318
491 + 31464827 = 31465318
509 + 31464809 = 31465318
587 + 31464731 = 31465318
617 + 31464701 = 31465318
701 + 31464617 = 31465318
761 + 31464557 = 31465318

Showing the first eight; more decompositions exist.
