Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552260, here are decompositions:

7 + 31552253 = 31552260
23 + 31552237 = 31552260
31 + 31552229 = 31552260
53 + 31552207 = 31552260
67 + 31552193 = 31552260
191 + 31552069 = 31552260
211 + 31552049 = 31552260
227 + 31552033 = 31552260

Showing the first eight; more decompositions exist.
