Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551622, here are decompositions:

23 + 31551599 = 31551622
29 + 31551593 = 31551622
83 + 31551539 = 31551622
191 + 31551431 = 31551622
269 + 31551353 = 31551622
281 + 31551341 = 31551622
293 + 31551329 = 31551622
419 + 31551203 = 31551622

Showing the first eight; more decompositions exist.
