Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465510, here are decompositions:

29 + 31465481 = 31465510
59 + 31465451 = 31465510
317 + 31465193 = 31465510
449 + 31465061 = 31465510
563 + 31464947 = 31465510
569 + 31464941 = 31465510
683 + 31464827 = 31465510
701 + 31464809 = 31465510

Showing the first eight; more decompositions exist.
