Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552386, here are decompositions:

83 + 31552303 = 31552386
149 + 31552237 = 31552386
157 + 31552229 = 31552386
179 + 31552207 = 31552386
193 + 31552193 = 31552386
317 + 31552069 = 31552386
337 + 31552049 = 31552386
353 + 31552033 = 31552386

Showing the first eight; more decompositions exist.
