Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593622, here are decompositions:

59 + 31593563 = 31593622
89 + 31593533 = 31593622
131 + 31593491 = 31593622
233 + 31593389 = 31593622
449 + 31593173 = 31593622
701 + 31592921 = 31593622
773 + 31592849 = 31593622
971 + 31592651 = 31593622

Showing the first eight; more decompositions exist.
