Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465162, here are decompositions:

101 + 31465061 = 31465162
353 + 31464809 = 31465162
431 + 31464731 = 31465162
461 + 31464701 = 31465162
653 + 31464509 = 31465162
719 + 31464443 = 31465162
761 + 31464401 = 31465162
821 + 31464341 = 31465162

Showing the first eight; more decompositions exist.
