Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522372, here are decompositions:

41 + 31522331 = 31522372
59 + 31522313 = 31522372
131 + 31522241 = 31522372
191 + 31522181 = 31522372
269 + 31522103 = 31522372
281 + 31522091 = 31522372
311 + 31522061 = 31522372
353 + 31522019 = 31522372

Showing the first eight; more decompositions exist.
