Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588622, here are decompositions:

19 + 31588603 = 31588622
61 + 31588561 = 31588622
139 + 31588483 = 31588622
151 + 31588471 = 31588622
181 + 31588441 = 31588622
223 + 31588399 = 31588622
271 + 31588351 = 31588622
421 + 31588201 = 31588622

Showing the first eight; more decompositions exist.
