Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614530, here are decompositions:

7 + 31614523 = 31614530
37 + 31614493 = 31614530
313 + 31614217 = 31614530
331 + 31614199 = 31614530
349 + 31614181 = 31614530
397 + 31614133 = 31614530
421 + 31614109 = 31614530
433 + 31614097 = 31614530

Showing the first eight; more decompositions exist.
