Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522774, here are decompositions:

191 + 31522583 = 31522774
233 + 31522541 = 31522774
251 + 31522523 = 31522774
281 + 31522493 = 31522774
401 + 31522373 = 31522774
443 + 31522331 = 31522774
461 + 31522313 = 31522774
593 + 31522181 = 31522774

Showing the first eight; more decompositions exist.
