Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596214, here are decompositions:

5 + 31596209 = 31596214
71 + 31596143 = 31596214
173 + 31596041 = 31596214
347 + 31595867 = 31596214
383 + 31595831 = 31596214
431 + 31595783 = 31596214
443 + 31595771 = 31596214
491 + 31595723 = 31596214

Showing the first eight; more decompositions exist.
