Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607222, here are decompositions:

271 + 31606951 = 31607222
541 + 31606681 = 31607222
571 + 31606651 = 31607222
643 + 31606579 = 31607222
811 + 31606411 = 31607222
853 + 31606369 = 31607222
883 + 31606339 = 31607222
1171 + 31606051 = 31607222

Showing the first eight; more decompositions exist.
