Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552150, here are decompositions:

11 + 31552139 = 31552150
23 + 31552127 = 31552150
101 + 31552049 = 31552150
131 + 31552019 = 31552150
173 + 31551977 = 31552150
191 + 31551959 = 31552150
293 + 31551857 = 31552150
347 + 31551803 = 31552150

Showing the first eight; more decompositions exist.
