Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593842, here are decompositions:

3 + 31593839 = 31593842
79 + 31593763 = 31593842
139 + 31593703 = 31593842
199 + 31593643 = 31593842
211 + 31593631 = 31593842
229 + 31593613 = 31593842
271 + 31593571 = 31593842
331 + 31593511 = 31593842

Showing the first eight; more decompositions exist.
