Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599746, here are decompositions:

19 + 31599727 = 31599746
43 + 31599703 = 31599746
97 + 31599649 = 31599746
193 + 31599553 = 31599746
307 + 31599439 = 31599746
397 + 31599349 = 31599746
433 + 31599313 = 31599746
439 + 31599307 = 31599746

Showing the first eight; more decompositions exist.
