Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529706, here are decompositions:

29 + 31529677 = 31529706
37 + 31529669 = 31529706
83 + 31529623 = 31529706
113 + 31529593 = 31529706
139 + 31529567 = 31529706
149 + 31529557 = 31529706
167 + 31529539 = 31529706
199 + 31529507 = 31529706

Showing the first eight; more decompositions exist.
