Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468758, here are decompositions:

31 + 31468727 = 31468758
59 + 31468699 = 31468758
127 + 31468631 = 31468758
199 + 31468559 = 31468758
229 + 31468529 = 31468758
241 + 31468517 = 31468758
311 + 31468447 = 31468758
359 + 31468399 = 31468758

Showing the first eight; more decompositions exist.
