Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552584, here are decompositions:

5 + 31552579 = 31552584
31 + 31552553 = 31552584
47 + 31552537 = 31552584
97 + 31552487 = 31552584
163 + 31552421 = 31552584
181 + 31552403 = 31552584
191 + 31552393 = 31552584
197 + 31552387 = 31552584

Showing the first eight; more decompositions exist.
