Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552648, here are decompositions:

5 + 31552643 = 31552648
59 + 31552589 = 31552648
227 + 31552421 = 31552648
419 + 31552229 = 31552648
509 + 31552139 = 31552648
521 + 31552127 = 31552648
599 + 31552049 = 31552648
821 + 31551827 = 31552648

Showing the first eight; more decompositions exist.
