Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614444, here are decompositions:

67 + 31614377 = 31614444
73 + 31614371 = 31614444
101 + 31614343 = 31614444
167 + 31614277 = 31614444
227 + 31614217 = 31614444
233 + 31614211 = 31614444
263 + 31614181 = 31614444
271 + 31614173 = 31614444

Showing the first eight; more decompositions exist.
