Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605004, here are decompositions:

3 + 31605001 = 31605004
17 + 31604987 = 31605004
71 + 31604933 = 31605004
257 + 31604747 = 31605004
281 + 31604723 = 31605004
317 + 31604687 = 31605004
401 + 31604603 = 31605004
443 + 31604561 = 31605004

Showing the first eight; more decompositions exist.
