Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541614, here are decompositions:

3 + 31541611 = 31541614
17 + 31541597 = 31541614
23 + 31541591 = 31541614
107 + 31541507 = 31541614
131 + 31541483 = 31541614
197 + 31541417 = 31541614
317 + 31541297 = 31541614
347 + 31541267 = 31541614

Showing the first eight; more decompositions exist.
