Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530706, here are decompositions:

3 + 31530703 = 31530706
5 + 31530701 = 31530706
23 + 31530683 = 31530706
47 + 31530659 = 31530706
89 + 31530617 = 31530706
113 + 31530593 = 31530706
227 + 31530479 = 31530706
269 + 31530437 = 31530706

Showing the first eight; more decompositions exist.
