Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562828, here are decompositions:

61 + 31562767 = 31562828
151 + 31562677 = 31562828
211 + 31562617 = 31562828
277 + 31562551 = 31562828
379 + 31562449 = 31562828
397 + 31562431 = 31562828
439 + 31562389 = 31562828
499 + 31562329 = 31562828

Showing the first eight; more decompositions exist.
