Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552498, here are decompositions:

11 + 31552487 = 31552498
227 + 31552271 = 31552498
269 + 31552229 = 31552498
359 + 31552139 = 31552498
449 + 31552049 = 31552498
479 + 31552019 = 31552498
521 + 31551977 = 31552498
557 + 31551941 = 31552498

Showing the first eight; more decompositions exist.
