Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482612, here are decompositions:

13 + 31482599 = 31482612
43 + 31482569 = 31482612
53 + 31482559 = 31482612
61 + 31482551 = 31482612
101 + 31482511 = 31482612
103 + 31482509 = 31482612
113 + 31482499 = 31482612
173 + 31482439 = 31482612

Showing the first eight; more decompositions exist.
