Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621922, here are decompositions:

43 + 31621879 = 31621922
229 + 31621693 = 31621922
271 + 31621651 = 31621922
331 + 31621591 = 31621922
421 + 31621501 = 31621922
523 + 31621399 = 31621922
859 + 31621063 = 31621922
991 + 31620931 = 31621922

Showing the first eight; more decompositions exist.
