Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552606, here are decompositions:

3 + 31552603 = 31552606
17 + 31552589 = 31552606
53 + 31552553 = 31552606
353 + 31552253 = 31552606
467 + 31552139 = 31552606
479 + 31552127 = 31552606
557 + 31552049 = 31552606
587 + 31552019 = 31552606

Showing the first eight; more decompositions exist.
