Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562796, here are decompositions:

17 + 31562779 = 31562796
19 + 31562777 = 31562796
29 + 31562767 = 31562796
59 + 31562737 = 31562796
113 + 31562683 = 31562796
173 + 31562623 = 31562796
179 + 31562617 = 31562796
193 + 31562603 = 31562796

Showing the first eight; more decompositions exist.
