Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507614, here are decompositions:

7 + 31507607 = 31507614
23 + 31507591 = 31507614
31 + 31507583 = 31507614
37 + 31507577 = 31507614
41 + 31507573 = 31507614
43 + 31507571 = 31507614
53 + 31507561 = 31507614
107 + 31507507 = 31507614

Showing the first eight; more decompositions exist.
