Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530046, here are decompositions:

3 + 31530043 = 31530046
17 + 31530029 = 31530046
29 + 31530017 = 31530046
113 + 31529933 = 31530046
227 + 31529819 = 31530046
263 + 31529783 = 31530046
479 + 31529567 = 31530046
599 + 31529447 = 31530046

Showing the first eight; more decompositions exist.
