Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465528, here are decompositions:

47 + 31465481 = 31465528
137 + 31465391 = 31465528
239 + 31465289 = 31465528
467 + 31465061 = 31465528
587 + 31464941 = 31465528
701 + 31464827 = 31465528
719 + 31464809 = 31465528
797 + 31464731 = 31465528

Showing the first eight; more decompositions exist.
