Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529622, here are decompositions:

29 + 31529593 = 31529622
71 + 31529551 = 31529622
83 + 31529539 = 31529622
101 + 31529521 = 31529622
151 + 31529471 = 31529622
191 + 31529431 = 31529622
263 + 31529359 = 31529622
269 + 31529353 = 31529622

Showing the first eight; more decompositions exist.
