Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530106, here are decompositions:

89 + 31530017 = 31530106
137 + 31529969 = 31530106
173 + 31529933 = 31530106
263 + 31529843 = 31530106
389 + 31529717 = 31530106
599 + 31529507 = 31530106
659 + 31529447 = 31530106
827 + 31529279 = 31530106

Showing the first eight; more decompositions exist.
