Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593542, here are decompositions:

31 + 31593511 = 31593542
151 + 31593391 = 31593542
199 + 31593343 = 31593542
229 + 31593313 = 31593542
349 + 31593193 = 31593542
433 + 31593109 = 31593542
571 + 31592971 = 31593542
619 + 31592923 = 31593542

Showing the first eight; more decompositions exist.
