Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526660, here are decompositions:

13 + 31526647 = 31526660
43 + 31526617 = 31526660
97 + 31526563 = 31526660
127 + 31526533 = 31526660
157 + 31526503 = 31526660
163 + 31526497 = 31526660
229 + 31526431 = 31526660
241 + 31526419 = 31526660

Showing the first eight; more decompositions exist.
