Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522652, here are decompositions:

19 + 31522633 = 31522652
61 + 31522591 = 31522652
103 + 31522549 = 31522652
193 + 31522459 = 31522652
211 + 31522441 = 31522652
241 + 31522411 = 31522652
313 + 31522339 = 31522652
409 + 31522243 = 31522652

Showing the first eight; more decompositions exist.
