Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552612, here are decompositions:

23 + 31552589 = 31552612
59 + 31552553 = 31552612
191 + 31552421 = 31552612
359 + 31552253 = 31552612
383 + 31552229 = 31552612
401 + 31552211 = 31552612
419 + 31552193 = 31552612
563 + 31552049 = 31552612

Showing the first eight; more decompositions exist.
