Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504626, here are decompositions:

7 + 31504619 = 31504626
19 + 31504607 = 31504626
53 + 31504573 = 31504626
59 + 31504567 = 31504626
79 + 31504547 = 31504626
173 + 31504453 = 31504626
239 + 31504387 = 31504626
269 + 31504357 = 31504626

Showing the first eight; more decompositions exist.
