Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604862, here are decompositions:

13 + 31604849 = 31604862
59 + 31604803 = 31604862
73 + 31604789 = 31604862
103 + 31604759 = 31604862
131 + 31604731 = 31604862
139 + 31604723 = 31604862
173 + 31604689 = 31604862
181 + 31604681 = 31604862

Showing the first eight; more decompositions exist.
