Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468926, here are decompositions:

7 + 31468919 = 31468926
23 + 31468903 = 31468926
103 + 31468823 = 31468926
149 + 31468777 = 31468926
199 + 31468727 = 31468926
227 + 31468699 = 31468926
337 + 31468589 = 31468926
353 + 31468573 = 31468926

Showing the first eight; more decompositions exist.
