Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552266, here are decompositions:

13 + 31552253 = 31552266
29 + 31552237 = 31552266
37 + 31552229 = 31552266
59 + 31552207 = 31552266
73 + 31552193 = 31552266
127 + 31552139 = 31552266
139 + 31552127 = 31552266
197 + 31552069 = 31552266

Showing the first eight; more decompositions exist.
