Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562696, here are decompositions:

13 + 31562683 = 31562696
19 + 31562677 = 31562696
73 + 31562623 = 31562696
79 + 31562617 = 31562696
103 + 31562593 = 31562696
229 + 31562467 = 31562696
307 + 31562389 = 31562696
349 + 31562347 = 31562696

Showing the first eight; more decompositions exist.
