Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621952, here are decompositions:

3 + 31621949 = 31621952
73 + 31621879 = 31621952
199 + 31621753 = 31621952
283 + 31621669 = 31621952
331 + 31621621 = 31621952
421 + 31621531 = 31621952
811 + 31621141 = 31621952
829 + 31621123 = 31621952

Showing the first eight; more decompositions exist.
