Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529926, here are decompositions:

3 + 31529923 = 31529926
83 + 31529843 = 31529926
107 + 31529819 = 31529926
257 + 31529669 = 31529926
359 + 31529567 = 31529926
419 + 31529507 = 31529926
479 + 31529447 = 31529926
647 + 31529279 = 31529926

Showing the first eight; more decompositions exist.
