Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552320, here are decompositions:

11 + 31552309 = 31552320
17 + 31552303 = 31552320
67 + 31552253 = 31552320
83 + 31552237 = 31552320
109 + 31552211 = 31552320
113 + 31552207 = 31552320
127 + 31552193 = 31552320
181 + 31552139 = 31552320

Showing the first eight; more decompositions exist.
