Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604044, here are decompositions:

11 + 31604033 = 31604044
53 + 31603991 = 31604044
113 + 31603931 = 31604044
167 + 31603877 = 31604044
293 + 31603751 = 31604044
401 + 31603643 = 31604044
431 + 31603613 = 31604044
467 + 31603577 = 31604044

Showing the first eight; more decompositions exist.
