Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626294, here are decompositions:

47 + 31626247 = 31626294
61 + 31626233 = 31626294
97 + 31626197 = 31626294
101 + 31626193 = 31626294
103 + 31626191 = 31626294
127 + 31626167 = 31626294
163 + 31626131 = 31626294
241 + 31626053 = 31626294

Showing the first eight; more decompositions exist.
