Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598758, here are decompositions:

5 + 31598753 = 31598758
41 + 31598717 = 31598758
71 + 31598687 = 31598758
89 + 31598669 = 31598758
167 + 31598591 = 31598758
239 + 31598519 = 31598758
431 + 31598327 = 31598758
479 + 31598279 = 31598758

Showing the first eight; more decompositions exist.
