Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552332, here are decompositions:

23 + 31552309 = 31552332
29 + 31552303 = 31552332
61 + 31552271 = 31552332
79 + 31552253 = 31552332
103 + 31552229 = 31552332
139 + 31552193 = 31552332
193 + 31552139 = 31552332
263 + 31552069 = 31552332

Showing the first eight; more decompositions exist.
