Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627302, here are decompositions:

13 + 31627289 = 31627302
41 + 31627261 = 31627302
53 + 31627249 = 31627302
59 + 31627243 = 31627302
101 + 31627201 = 31627302
151 + 31627151 = 31627302
181 + 31627121 = 31627302
211 + 31627091 = 31627302

Showing the first eight; more decompositions exist.
