Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508446, here are decompositions:

3 + 31508443 = 31508446
29 + 31508417 = 31508446
83 + 31508363 = 31508446
269 + 31508177 = 31508446
293 + 31508153 = 31508446
353 + 31508093 = 31508446
419 + 31508027 = 31508446
443 + 31508003 = 31508446

Showing the first eight; more decompositions exist.
