Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593236, here are decompositions:

43 + 31593193 = 31593236
127 + 31593109 = 31593236
139 + 31593097 = 31593236
277 + 31592959 = 31593236
313 + 31592923 = 31593236
439 + 31592797 = 31593236
457 + 31592779 = 31593236
463 + 31592773 = 31593236

Showing the first eight; more decompositions exist.
