Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593482, here are decompositions:

3 + 31593479 = 31593482
139 + 31593343 = 31593482
229 + 31593253 = 31593482
373 + 31593109 = 31593482
499 + 31592983 = 31593482
523 + 31592959 = 31593482
673 + 31592809 = 31593482
709 + 31592773 = 31593482

Showing the first eight; more decompositions exist.
