Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465036, here are decompositions:

3 + 31465033 = 31465036
89 + 31464947 = 31465036
227 + 31464809 = 31465036
419 + 31464617 = 31465036
479 + 31464557 = 31465036
593 + 31464443 = 31465036
677 + 31464359 = 31465036
887 + 31464149 = 31465036

Showing the first eight; more decompositions exist.
