Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465608, here are decompositions:

7 + 31465601 = 31465608
29 + 31465579 = 31465608
37 + 31465571 = 31465608
47 + 31465561 = 31465608
61 + 31465547 = 31465608
79 + 31465529 = 31465608
127 + 31465481 = 31465608
149 + 31465459 = 31465608

Showing the first eight; more decompositions exist.
