Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562498, here are decompositions:

31 + 31562467 = 31562498
67 + 31562431 = 31562498
109 + 31562389 = 31562498
151 + 31562347 = 31562498
199 + 31562299 = 31562498
241 + 31562257 = 31562498
379 + 31562119 = 31562498
571 + 31561927 = 31562498

Showing the first eight; more decompositions exist.
