Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614472, here are decompositions:

23 + 31614449 = 31614472
101 + 31614371 = 31614472
293 + 31614179 = 31614472
311 + 31614161 = 31614472
401 + 31614071 = 31614472
509 + 31613963 = 31614472
653 + 31613819 = 31614472
1031 + 31613441 = 31614472

Showing the first eight; more decompositions exist.
