Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552408, here are decompositions:

5 + 31552403 = 31552408
137 + 31552271 = 31552408
179 + 31552229 = 31552408
197 + 31552211 = 31552408
269 + 31552139 = 31552408
281 + 31552127 = 31552408
359 + 31552049 = 31552408
389 + 31552019 = 31552408

Showing the first eight; more decompositions exist.
