Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552636, here are decompositions:

47 + 31552589 = 31552636
83 + 31552553 = 31552636
149 + 31552487 = 31552636
233 + 31552403 = 31552636
383 + 31552253 = 31552636
443 + 31552193 = 31552636
509 + 31552127 = 31552636
587 + 31552049 = 31552636

Showing the first eight; more decompositions exist.
