Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604850, here are decompositions:

47 + 31604803 = 31604850
61 + 31604789 = 31604850
83 + 31604767 = 31604850
103 + 31604747 = 31604850
107 + 31604743 = 31604850
127 + 31604723 = 31604850
131 + 31604719 = 31604850
163 + 31604687 = 31604850

Showing the first eight; more decompositions exist.
