Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522726, here are decompositions:

113 + 31522613 = 31522726
173 + 31522553 = 31522726
197 + 31522529 = 31522726
233 + 31522493 = 31522726
293 + 31522433 = 31522726
353 + 31522373 = 31522726
449 + 31522277 = 31522726
479 + 31522247 = 31522726

Showing the first eight; more decompositions exist.
