Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614156, here are decompositions:

23 + 31614133 = 31614156
47 + 31614109 = 31614156
59 + 31614097 = 31614156
137 + 31614019 = 31614156
149 + 31614007 = 31614156
193 + 31613963 = 31614156
229 + 31613927 = 31614156
313 + 31613843 = 31614156

Showing the first eight; more decompositions exist.
