Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627332, here are decompositions:

13 + 31627319 = 31627332
29 + 31627303 = 31627332
43 + 31627289 = 31627332
71 + 31627261 = 31627332
83 + 31627249 = 31627332
89 + 31627243 = 31627332
131 + 31627201 = 31627332
181 + 31627151 = 31627332

Showing the first eight; more decompositions exist.
