Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481626, here are decompositions:

3 + 31481623 = 31481626
5 + 31481621 = 31481626
17 + 31481609 = 31481626
83 + 31481543 = 31481626
149 + 31481477 = 31481626
167 + 31481459 = 31481626
173 + 31481453 = 31481626
233 + 31481393 = 31481626

Showing the first eight; more decompositions exist.
