Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599238, here are decompositions:

137 + 31599101 = 31599238
179 + 31599059 = 31599238
311 + 31598927 = 31599238
449 + 31598789 = 31599238
467 + 31598771 = 31599238
521 + 31598717 = 31599238
569 + 31598669 = 31599238
647 + 31598591 = 31599238

Showing the first eight; more decompositions exist.
