Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593458, here are decompositions:

67 + 31593391 = 31593458
151 + 31593307 = 31593458
349 + 31593109 = 31593458
487 + 31592971 = 31593458
499 + 31592959 = 31593458
661 + 31592797 = 31593458
859 + 31592599 = 31593458
907 + 31592551 = 31593458

Showing the first eight; more decompositions exist.
