Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497622, here are decompositions:

53 + 31497569 = 31497622
71 + 31497551 = 31497622
131 + 31497491 = 31497622
173 + 31497449 = 31497622
179 + 31497443 = 31497622
263 + 31497359 = 31497622
269 + 31497353 = 31497622
281 + 31497341 = 31497622

Showing the first eight; more decompositions exist.
