Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465610, here are decompositions:

31 + 31465579 = 31465610
151 + 31465459 = 31465610
193 + 31465417 = 31465610
367 + 31465243 = 31465610
433 + 31465177 = 31465610
457 + 31465153 = 31465610
487 + 31465123 = 31465610
499 + 31465111 = 31465610

Showing the first eight; more decompositions exist.
