Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522732, here are decompositions:

149 + 31522583 = 31522732
179 + 31522553 = 31522732
191 + 31522541 = 31522732
239 + 31522493 = 31522732
281 + 31522451 = 31522732
359 + 31522373 = 31522732
401 + 31522331 = 31522732
419 + 31522313 = 31522732

Showing the first eight; more decompositions exist.
