Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493364, here are decompositions:

11 + 31493353 = 31493364
17 + 31493347 = 31493364
41 + 31493323 = 31493364
43 + 31493321 = 31493364
73 + 31493291 = 31493364
113 + 31493251 = 31493364
163 + 31493201 = 31493364
173 + 31493191 = 31493364

Showing the first eight; more decompositions exist.
