Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605062, here are decompositions:

43 + 31605019 = 31605062
61 + 31605001 = 31605062
103 + 31604959 = 31605062
199 + 31604863 = 31605062
331 + 31604731 = 31605062
373 + 31604689 = 31605062
421 + 31604641 = 31605062
691 + 31604371 = 31605062

Showing the first eight; more decompositions exist.
