Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497796, here are decompositions:

23 + 31497773 = 31497796
59 + 31497737 = 31497796
89 + 31497707 = 31497796
227 + 31497569 = 31497796
269 + 31497527 = 31497796
347 + 31497449 = 31497796
353 + 31497443 = 31497796
443 + 31497353 = 31497796

Showing the first eight; more decompositions exist.
