Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605074, here are decompositions:

3 + 31605071 = 31605074
73 + 31605001 = 31605074
211 + 31604863 = 31605074
271 + 31604803 = 31605074
307 + 31604767 = 31605074
331 + 31604743 = 31605074
433 + 31604641 = 31605074
463 + 31604611 = 31605074

Showing the first eight; more decompositions exist.
