Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562846, here are decompositions:

19 + 31562827 = 31562846
67 + 31562779 = 31562846
79 + 31562767 = 31562846
109 + 31562737 = 31562846
163 + 31562683 = 31562846
223 + 31562623 = 31562846
229 + 31562617 = 31562846
379 + 31562467 = 31562846

Showing the first eight; more decompositions exist.
