Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614802, here are decompositions:

5 + 31614797 = 31614802
101 + 31614701 = 31614802
239 + 31614563 = 31614802
251 + 31614551 = 31614802
353 + 31614449 = 31614802
431 + 31614371 = 31614802
449 + 31614353 = 31614802
641 + 31614161 = 31614802

Showing the first eight; more decompositions exist.
