Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552248, here are decompositions:

11 + 31552237 = 31552248
19 + 31552229 = 31552248
37 + 31552211 = 31552248
41 + 31552207 = 31552248
109 + 31552139 = 31552248
179 + 31552069 = 31552248
191 + 31552057 = 31552248
199 + 31552049 = 31552248

Showing the first eight; more decompositions exist.
