Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552512, here are decompositions:

23 + 31552489 = 31552512
83 + 31552429 = 31552512
109 + 31552403 = 31552512
241 + 31552271 = 31552512
283 + 31552229 = 31552512
373 + 31552139 = 31552512
443 + 31552069 = 31552512
463 + 31552049 = 31552512

Showing the first eight; more decompositions exist.
