Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552356, here are decompositions:

5 + 31552351 = 31552356
47 + 31552309 = 31552356
53 + 31552303 = 31552356
103 + 31552253 = 31552356
127 + 31552229 = 31552356
149 + 31552207 = 31552356
163 + 31552193 = 31552356
229 + 31552127 = 31552356

Showing the first eight; more decompositions exist.
