Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552288, here are decompositions:

17 + 31552271 = 31552288
59 + 31552229 = 31552288
149 + 31552139 = 31552288
239 + 31552049 = 31552288
269 + 31552019 = 31552288
311 + 31551977 = 31552288
347 + 31551941 = 31552288
431 + 31551857 = 31552288

Showing the first eight; more decompositions exist.
