Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464904, here are decompositions:

83 + 31464821 = 31464904
173 + 31464731 = 31464904
347 + 31464557 = 31464904
461 + 31464443 = 31464904
503 + 31464401 = 31464904
563 + 31464341 = 31464904
761 + 31464143 = 31464904
857 + 31464047 = 31464904

Showing the first eight; more decompositions exist.
