Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593442, here are decompositions:

5 + 31593437 = 31593442
53 + 31593389 = 31593442
191 + 31593251 = 31593442
269 + 31593173 = 31593442
431 + 31593011 = 31593442
449 + 31592993 = 31593442
521 + 31592921 = 31593442
593 + 31592849 = 31593442

Showing the first eight; more decompositions exist.
