Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493616, here are decompositions:

5 + 31493611 = 31493616
17 + 31493599 = 31493616
23 + 31493593 = 31493616
43 + 31493573 = 31493616
47 + 31493569 = 31493616
59 + 31493557 = 31493616
83 + 31493533 = 31493616
97 + 31493519 = 31493616

Showing the first eight; more decompositions exist.
