Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592090, here are decompositions:

37 + 31592053 = 31592090
43 + 31592047 = 31592090
97 + 31591993 = 31592090
181 + 31591909 = 31592090
223 + 31591867 = 31592090
307 + 31591783 = 31592090
367 + 31591723 = 31592090
379 + 31591711 = 31592090

Showing the first eight; more decompositions exist.
