Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522626, here are decompositions:

13 + 31522613 = 31522626
29 + 31522597 = 31522626
43 + 31522583 = 31522626
73 + 31522553 = 31522626
97 + 31522529 = 31522626
103 + 31522523 = 31522626
167 + 31522459 = 31522626
193 + 31522433 = 31522626

Showing the first eight; more decompositions exist.
