Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522424, here are decompositions:

13 + 31522411 = 31522424
61 + 31522363 = 31522424
67 + 31522357 = 31522424
97 + 31522327 = 31522424
127 + 31522297 = 31522424
181 + 31522243 = 31522424
433 + 31521991 = 31522424
541 + 31521883 = 31522424

Showing the first eight; more decompositions exist.
