Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452610, here are decompositions:

3 + 31452607 = 31452610
11 + 31452599 = 31452610
23 + 31452587 = 31452610
71 + 31452539 = 31452610
83 + 31452527 = 31452610
89 + 31452521 = 31452610
113 + 31452497 = 31452610
149 + 31452461 = 31452610

Showing the first eight; more decompositions exist.
