Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523768, here are decompositions:

7 + 31523761 = 31523768
19 + 31523749 = 31523768
61 + 31523707 = 31523768
109 + 31523659 = 31523768
229 + 31523539 = 31523768
307 + 31523461 = 31523768
349 + 31523419 = 31523768
421 + 31523347 = 31523768

Showing the first eight; more decompositions exist.
