Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626334, here are decompositions:

11 + 31626323 = 31626334
101 + 31626233 = 31626334
137 + 31626197 = 31626334
167 + 31626167 = 31626334
281 + 31626053 = 31626334
293 + 31626041 = 31626334
347 + 31625987 = 31626334
353 + 31625981 = 31626334

Showing the first eight; more decompositions exist.
