Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452660, here are decompositions:

11 + 31452649 = 31452660
37 + 31452623 = 31452660
53 + 31452607 = 31452660
61 + 31452599 = 31452660
73 + 31452587 = 31452660
89 + 31452571 = 31452660
131 + 31452529 = 31452660
139 + 31452521 = 31452660

Showing the first eight; more decompositions exist.
