Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552246, here are decompositions:

17 + 31552229 = 31552246
53 + 31552193 = 31552246
107 + 31552139 = 31552246
197 + 31552049 = 31552246
227 + 31552019 = 31552246
269 + 31551977 = 31552246
389 + 31551857 = 31552246
419 + 31551827 = 31552246

Showing the first eight; more decompositions exist.
