Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614620, here are decompositions:

19 + 31614601 = 31614620
61 + 31614559 = 31614620
73 + 31614547 = 31614620
97 + 31614523 = 31614620
127 + 31614493 = 31614620
277 + 31614343 = 31614620
337 + 31614283 = 31614620
409 + 31614211 = 31614620

Showing the first eight; more decompositions exist.
