Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464832, here are decompositions:

5 + 31464827 = 31464832
11 + 31464821 = 31464832
23 + 31464809 = 31464832
101 + 31464731 = 31464832
131 + 31464701 = 31464832
251 + 31464581 = 31464832
389 + 31464443 = 31464832
431 + 31464401 = 31464832

Showing the first eight; more decompositions exist.
