Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552030, here are decompositions:

11 + 31552019 = 31552030
53 + 31551977 = 31552030
71 + 31551959 = 31552030
89 + 31551941 = 31552030
173 + 31551857 = 31552030
227 + 31551803 = 31552030
347 + 31551683 = 31552030
359 + 31551671 = 31552030

Showing the first eight; more decompositions exist.
