Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522904, here are decompositions:

3 + 31522901 = 31522904
31 + 31522873 = 31522904
157 + 31522747 = 31522904
211 + 31522693 = 31522904
241 + 31522663 = 31522904
271 + 31522633 = 31522904
307 + 31522597 = 31522904
313 + 31522591 = 31522904

Showing the first eight; more decompositions exist.
