Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599274, here are decompositions:

101 + 31599173 = 31599274
173 + 31599101 = 31599274
347 + 31598927 = 31599274
401 + 31598873 = 31599274
491 + 31598783 = 31599274
503 + 31598771 = 31599274
521 + 31598753 = 31599274
557 + 31598717 = 31599274

Showing the first eight; more decompositions exist.
