Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539446, here are decompositions:

7 + 31539439 = 31539446
79 + 31539367 = 31539446
97 + 31539349 = 31539446
109 + 31539337 = 31539446
157 + 31539289 = 31539446
163 + 31539283 = 31539446
283 + 31539163 = 31539446
373 + 31539073 = 31539446

Showing the first eight; more decompositions exist.
