Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522952, here are decompositions:

79 + 31522873 = 31522952
283 + 31522669 = 31522952
541 + 31522411 = 31522952
613 + 31522339 = 31522952
709 + 31522243 = 31522952
733 + 31522219 = 31522952
823 + 31522129 = 31522952
1069 + 31521883 = 31522952

Showing the first eight; more decompositions exist.
