Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627248, here are decompositions:

5 + 31627243 = 31627248
11 + 31627237 = 31627248
31 + 31627217 = 31627248
47 + 31627201 = 31627248
97 + 31627151 = 31627248
127 + 31627121 = 31627248
157 + 31627091 = 31627248
179 + 31627069 = 31627248

Showing the first eight; more decompositions exist.
