Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462626, here are decompositions:

17 + 31462609 = 31462626
23 + 31462603 = 31462626
37 + 31462589 = 31462626
43 + 31462583 = 31462626
47 + 31462579 = 31462626
53 + 31462573 = 31462626
73 + 31462553 = 31462626
79 + 31462547 = 31462626

Showing the first eight; more decompositions exist.
