Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562396, here are decompositions:

7 + 31562389 = 31562396
67 + 31562329 = 31562396
97 + 31562299 = 31562396
139 + 31562257 = 31562396
277 + 31562119 = 31562396
373 + 31562023 = 31562396
379 + 31562017 = 31562396
457 + 31561939 = 31562396

Showing the first eight; more decompositions exist.
