Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477226, here are decompositions:

13 + 31477213 = 31477226
19 + 31477207 = 31477226
127 + 31477099 = 31477226
163 + 31477063 = 31477226
199 + 31477027 = 31477226
373 + 31476853 = 31477226
379 + 31476847 = 31477226
397 + 31476829 = 31477226

Showing the first eight; more decompositions exist.
