Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452606, here are decompositions:

7 + 31452599 = 31452606
19 + 31452587 = 31452606
23 + 31452583 = 31452606
67 + 31452539 = 31452606
79 + 31452527 = 31452606
89 + 31452517 = 31452606
109 + 31452497 = 31452606
113 + 31452493 = 31452606

Showing the first eight; more decompositions exist.
