Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607444, here are decompositions:

103 + 31607341 = 31607444
151 + 31607293 = 31607444
163 + 31607281 = 31607444
181 + 31607263 = 31607444
307 + 31607137 = 31607444
397 + 31607047 = 31607444
487 + 31606957 = 31607444
541 + 31606903 = 31607444

Showing the first eight; more decompositions exist.
