Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604742, here are decompositions:

11 + 31604731 = 31604742
19 + 31604723 = 31604742
23 + 31604719 = 31604742
53 + 31604689 = 31604742
61 + 31604681 = 31604742
101 + 31604641 = 31604742
131 + 31604611 = 31604742
139 + 31604603 = 31604742

Showing the first eight; more decompositions exist.
