Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514622, here are decompositions:

23 + 31514599 = 31514622
43 + 31514579 = 31514622
71 + 31514551 = 31514622
89 + 31514533 = 31514622
109 + 31514513 = 31514622
149 + 31514473 = 31514622
173 + 31514449 = 31514622
193 + 31514429 = 31514622

Showing the first eight; more decompositions exist.
