Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552338, here are decompositions:

29 + 31552309 = 31552338
67 + 31552271 = 31552338
101 + 31552237 = 31552338
109 + 31552229 = 31552338
127 + 31552211 = 31552338
131 + 31552207 = 31552338
199 + 31552139 = 31552338
211 + 31552127 = 31552338

Showing the first eight; more decompositions exist.
