Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552450, here are decompositions:

29 + 31552421 = 31552450
47 + 31552403 = 31552450
179 + 31552271 = 31552450
197 + 31552253 = 31552450
239 + 31552211 = 31552450
257 + 31552193 = 31552450
311 + 31552139 = 31552450
401 + 31552049 = 31552450

Showing the first eight; more decompositions exist.
