Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593042, here are decompositions:

11 + 31593031 = 31593042
31 + 31593011 = 31593042
59 + 31592983 = 31593042
71 + 31592971 = 31593042
83 + 31592959 = 31593042
193 + 31592849 = 31593042
199 + 31592843 = 31593042
233 + 31592809 = 31593042

Showing the first eight; more decompositions exist.
