Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522808, here are decompositions:

61 + 31522747 = 31522808
139 + 31522669 = 31522808
151 + 31522657 = 31522808
211 + 31522597 = 31522808
349 + 31522459 = 31522808
367 + 31522441 = 31522808
397 + 31522411 = 31522808
601 + 31522207 = 31522808

Showing the first eight; more decompositions exist.
