Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471626, here are decompositions:

5 + 31471621 = 31471626
47 + 31471579 = 31471626
103 + 31471523 = 31471626
157 + 31471469 = 31471626
229 + 31471397 = 31471626
239 + 31471387 = 31471626
269 + 31471357 = 31471626
337 + 31471289 = 31471626

Showing the first eight; more decompositions exist.
