Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514574, here are decompositions:

23 + 31514551 = 31514574
37 + 31514537 = 31514574
41 + 31514533 = 31514574
61 + 31514513 = 31514574
97 + 31514477 = 31514574
101 + 31514473 = 31514574
151 + 31514423 = 31514574
173 + 31514401 = 31514574

Showing the first eight; more decompositions exist.
