Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598746, here are decompositions:

29 + 31598717 = 31598746
59 + 31598687 = 31598746
227 + 31598519 = 31598746
233 + 31598513 = 31598746
383 + 31598363 = 31598746
419 + 31598327 = 31598746
467 + 31598279 = 31598746
479 + 31598267 = 31598746

Showing the first eight; more decompositions exist.
