Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552302, here are decompositions:

31 + 31552271 = 31552302
73 + 31552229 = 31552302
109 + 31552193 = 31552302
163 + 31552139 = 31552302
233 + 31552069 = 31552302
269 + 31552033 = 31552302
283 + 31552019 = 31552302
401 + 31551901 = 31552302

Showing the first eight; more decompositions exist.
