Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617484, here are decompositions:

23 + 31617461 = 31617484
53 + 31617431 = 31617484
71 + 31617413 = 31617484
113 + 31617371 = 31617484
191 + 31617293 = 31617484
233 + 31617251 = 31617484
317 + 31617167 = 31617484
383 + 31617101 = 31617484

Showing the first eight; more decompositions exist.
