Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562606, here are decompositions:

3 + 31562603 = 31562606
13 + 31562593 = 31562606
139 + 31562467 = 31562606
157 + 31562449 = 31562606
277 + 31562329 = 31562606
307 + 31562299 = 31562606
349 + 31562257 = 31562606
487 + 31562119 = 31562606

Showing the first eight; more decompositions exist.
