Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529010, here are decompositions:

13 + 31528997 = 31529010
17 + 31528993 = 31529010
41 + 31528969 = 31529010
43 + 31528967 = 31529010
101 + 31528909 = 31529010
157 + 31528853 = 31529010
167 + 31528843 = 31529010
179 + 31528831 = 31529010

Showing the first eight; more decompositions exist.
