Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593248, here are decompositions:

139 + 31593109 = 31593248
151 + 31593097 = 31593248
277 + 31592971 = 31593248
439 + 31592809 = 31593248
487 + 31592761 = 31593248
571 + 31592677 = 31593248
607 + 31592641 = 31593248
691 + 31592557 = 31593248

Showing the first eight; more decompositions exist.
