Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614624, here are decompositions:

23 + 31614601 = 31614624
37 + 31614587 = 31614624
61 + 31614563 = 31614624
73 + 31614551 = 31614624
101 + 31614523 = 31614624
131 + 31614493 = 31614624
271 + 31614353 = 31614624
281 + 31614343 = 31614624

Showing the first eight; more decompositions exist.
