Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508476, here are decompositions:

23 + 31508453 = 31508476
59 + 31508417 = 31508476
113 + 31508363 = 31508476
317 + 31508159 = 31508476
383 + 31508093 = 31508476
449 + 31508027 = 31508476
563 + 31507913 = 31508476
599 + 31507877 = 31508476

Showing the first eight; more decompositions exist.
