Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452666, here are decompositions:

17 + 31452649 = 31452666
43 + 31452623 = 31452666
59 + 31452607 = 31452666
67 + 31452599 = 31452666
79 + 31452587 = 31452666
83 + 31452583 = 31452666
127 + 31452539 = 31452666
137 + 31452529 = 31452666

Showing the first eight; more decompositions exist.
