Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493836, here are decompositions:

47 + 31493789 = 31493836
53 + 31493783 = 31493836
263 + 31493573 = 31493836
317 + 31493519 = 31493836
359 + 31493477 = 31493836
389 + 31493447 = 31493836
587 + 31493249 = 31493836
683 + 31493153 = 31493836

Showing the first eight; more decompositions exist.
