Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486934, here are decompositions:

7 + 31486927 = 31486934
211 + 31486723 = 31486934
223 + 31486711 = 31486934
277 + 31486657 = 31486934
307 + 31486627 = 31486934
331 + 31486603 = 31486934
397 + 31486537 = 31486934
541 + 31486393 = 31486934

Showing the first eight; more decompositions exist.
