Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493764, here are decompositions:

47 + 31493717 = 31493764
53 + 31493711 = 31493764
191 + 31493573 = 31493764
251 + 31493513 = 31493764
317 + 31493447 = 31493764
443 + 31493321 = 31493764
563 + 31493201 = 31493764
593 + 31493171 = 31493764

Showing the first eight; more decompositions exist.
