Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560350, here are decompositions:

7 + 31560343 = 31560350
43 + 31560307 = 31560350
103 + 31560247 = 31560350
271 + 31560079 = 31560350
277 + 31560073 = 31560350
331 + 31560019 = 31560350
373 + 31559977 = 31560350
439 + 31559911 = 31560350

Showing the first eight; more decompositions exist.
