Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522426, here are decompositions:

53 + 31522373 = 31522426
113 + 31522313 = 31522426
149 + 31522277 = 31522426
179 + 31522247 = 31522426
197 + 31522229 = 31522426
449 + 31521977 = 31522426
563 + 31521863 = 31522426
743 + 31521683 = 31522426

Showing the first eight; more decompositions exist.
