Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522632, here are decompositions:

19 + 31522613 = 31522632
41 + 31522591 = 31522632
79 + 31522553 = 31522632
83 + 31522549 = 31522632
103 + 31522529 = 31522632
109 + 31522523 = 31522632
139 + 31522493 = 31522632
173 + 31522459 = 31522632

Showing the first eight; more decompositions exist.
