Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493584, here are decompositions:

11 + 31493573 = 31493584
71 + 31493513 = 31493584
107 + 31493477 = 31493584
137 + 31493447 = 31493584
263 + 31493321 = 31493584
293 + 31493291 = 31493584
383 + 31493201 = 31493584
431 + 31493153 = 31493584

Showing the first eight; more decompositions exist.
