Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614272, here are decompositions:

43 + 31614229 = 31614272
61 + 31614211 = 31614272
73 + 31614199 = 31614272
139 + 31614133 = 31614272
163 + 31614109 = 31614272
181 + 31614091 = 31614272
211 + 31614061 = 31614272
271 + 31614001 = 31614272

Showing the first eight; more decompositions exist.
