Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522472, here are decompositions:

13 + 31522459 = 31522472
31 + 31522441 = 31522472
61 + 31522411 = 31522472
109 + 31522363 = 31522472
229 + 31522243 = 31522472
643 + 31521829 = 31522472
733 + 31521739 = 31522472
823 + 31521649 = 31522472

Showing the first eight; more decompositions exist.
