Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627272, here are decompositions:

11 + 31627261 = 31627272
23 + 31627249 = 31627272
29 + 31627243 = 31627272
71 + 31627201 = 31627272
139 + 31627133 = 31627272
151 + 31627121 = 31627272
181 + 31627091 = 31627272
199 + 31627073 = 31627272

Showing the first eight; more decompositions exist.
