Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627230, here are decompositions:

13 + 31627217 = 31627230
29 + 31627201 = 31627230
79 + 31627151 = 31627230
97 + 31627133 = 31627230
109 + 31627121 = 31627230
139 + 31627091 = 31627230
157 + 31627073 = 31627230
179 + 31627051 = 31627230

Showing the first eight; more decompositions exist.
