Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552536, here are decompositions:

47 + 31552489 = 31552536
107 + 31552429 = 31552536
149 + 31552387 = 31552536
227 + 31552309 = 31552536
233 + 31552303 = 31552536
283 + 31552253 = 31552536
307 + 31552229 = 31552536
397 + 31552139 = 31552536

Showing the first eight; more decompositions exist.
