Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474526, here are decompositions:

7 + 31474519 = 31474526
37 + 31474489 = 31474526
103 + 31474423 = 31474526
163 + 31474363 = 31474526
277 + 31474249 = 31474526
313 + 31474213 = 31474526
397 + 31474129 = 31474526
619 + 31473907 = 31474526

Showing the first eight; more decompositions exist.
