Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627704, here are decompositions:

103 + 31627601 = 31627704
127 + 31627577 = 31627704
131 + 31627573 = 31627704
137 + 31627567 = 31627704
167 + 31627537 = 31627704
193 + 31627511 = 31627704
293 + 31627411 = 31627704
313 + 31627391 = 31627704

Showing the first eight; more decompositions exist.
