Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626346, here are decompositions:

23 + 31626323 = 31626346
113 + 31626233 = 31626346
137 + 31626209 = 31626346
149 + 31626197 = 31626346
179 + 31626167 = 31626346
293 + 31626053 = 31626346
359 + 31625987 = 31626346
383 + 31625963 = 31626346

Showing the first eight; more decompositions exist.
