Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522882, here are decompositions:

59 + 31522823 = 31522882
269 + 31522613 = 31522882
353 + 31522529 = 31522882
359 + 31522523 = 31522882
389 + 31522493 = 31522882
431 + 31522451 = 31522882
449 + 31522433 = 31522882
509 + 31522373 = 31522882

Showing the first eight; more decompositions exist.
