Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562826, here are decompositions:

47 + 31562779 = 31562826
59 + 31562767 = 31562826
89 + 31562737 = 31562826
149 + 31562677 = 31562826
199 + 31562627 = 31562826
223 + 31562603 = 31562826
233 + 31562593 = 31562826
283 + 31562543 = 31562826

Showing the first eight; more decompositions exist.
