Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552620, here are decompositions:

17 + 31552603 = 31552620
31 + 31552589 = 31552620
41 + 31552579 = 31552620
67 + 31552553 = 31552620
83 + 31552537 = 31552620
131 + 31552489 = 31552620
191 + 31552429 = 31552620
199 + 31552421 = 31552620

Showing the first eight; more decompositions exist.
