Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462606, here are decompositions:

3 + 31462603 = 31462606
17 + 31462589 = 31462606
23 + 31462583 = 31462606
29 + 31462577 = 31462606
53 + 31462553 = 31462606
59 + 31462547 = 31462606
167 + 31462439 = 31462606
173 + 31462433 = 31462606

Showing the first eight; more decompositions exist.
