Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550262, here are decompositions:

5 + 31550257 = 31550262
11 + 31550251 = 31550262
41 + 31550221 = 31550262
61 + 31550201 = 31550262
83 + 31550179 = 31550262
109 + 31550153 = 31550262
113 + 31550149 = 31550262
131 + 31550131 = 31550262

Showing the first eight; more decompositions exist.
