Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519626, here are decompositions:

43 + 31519583 = 31519626
59 + 31519567 = 31519626
107 + 31519519 = 31519626
139 + 31519487 = 31519626
163 + 31519463 = 31519626
167 + 31519459 = 31519626
199 + 31519427 = 31519626
223 + 31519403 = 31519626

Showing the first eight; more decompositions exist.
