Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465674, here are decompositions:

11 + 31465663 = 31465674
13 + 31465661 = 31465674
43 + 31465631 = 31465674
73 + 31465601 = 31465674
103 + 31465571 = 31465674
113 + 31465561 = 31465674
127 + 31465547 = 31465674
193 + 31465481 = 31465674

Showing the first eight; more decompositions exist.
