Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593682, here are decompositions:

41 + 31593641 = 31593682
53 + 31593629 = 31593682
149 + 31593533 = 31593682
179 + 31593503 = 31593682
191 + 31593491 = 31593682
293 + 31593389 = 31593682
383 + 31593299 = 31593682
431 + 31593251 = 31593682

Showing the first eight; more decompositions exist.
