Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539404, here are decompositions:

3 + 31539401 = 31539404
37 + 31539367 = 31539404
67 + 31539337 = 31539404
73 + 31539331 = 31539404
163 + 31539241 = 31539404
241 + 31539163 = 31539404
331 + 31539073 = 31539404
397 + 31539007 = 31539404

Showing the first eight; more decompositions exist.
