Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552510, here are decompositions:

23 + 31552487 = 31552510
89 + 31552421 = 31552510
107 + 31552403 = 31552510
239 + 31552271 = 31552510
257 + 31552253 = 31552510
281 + 31552229 = 31552510
317 + 31552193 = 31552510
383 + 31552127 = 31552510

Showing the first eight; more decompositions exist.
