Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552672, here are decompositions:

29 + 31552643 = 31552672
83 + 31552589 = 31552672
251 + 31552421 = 31552672
269 + 31552403 = 31552672
401 + 31552271 = 31552672
419 + 31552253 = 31552672
443 + 31552229 = 31552672
461 + 31552211 = 31552672

Showing the first eight; more decompositions exist.
