Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515614, here are decompositions:

3 + 31515611 = 31515614
7 + 31515607 = 31515614
37 + 31515577 = 31515614
307 + 31515307 = 31515614
313 + 31515301 = 31515614
331 + 31515283 = 31515614
373 + 31515241 = 31515614
397 + 31515217 = 31515614

Showing the first eight; more decompositions exist.
