Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475626, here are decompositions:

3 + 31475623 = 31475626
29 + 31475597 = 31475626
47 + 31475579 = 31475626
137 + 31475489 = 31475626
167 + 31475459 = 31475626
173 + 31475453 = 31475626
197 + 31475429 = 31475626
233 + 31475393 = 31475626

Showing the first eight; more decompositions exist.
