Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552422, here are decompositions:

19 + 31552403 = 31552422
29 + 31552393 = 31552422
71 + 31552351 = 31552422
113 + 31552309 = 31552422
151 + 31552271 = 31552422
193 + 31552229 = 31552422
211 + 31552211 = 31552422
229 + 31552193 = 31552422

Showing the first eight; more decompositions exist.
