Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541714, here are decompositions:

7 + 31541707 = 31541714
37 + 31541677 = 31541714
103 + 31541611 = 31541714
151 + 31541563 = 31541714
157 + 31541557 = 31541714
277 + 31541437 = 31541714
313 + 31541401 = 31541714
367 + 31541347 = 31541714

Showing the first eight; more decompositions exist.
