Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593070, here are decompositions:

23 + 31593047 = 31593070
59 + 31593011 = 31593070
149 + 31592921 = 31593070
227 + 31592843 = 31593070
419 + 31592651 = 31593070
449 + 31592621 = 31593070
503 + 31592567 = 31593070
617 + 31592453 = 31593070

Showing the first eight; more decompositions exist.
