Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552726, here are decompositions:

5 + 31552721 = 31552726
17 + 31552709 = 31552726
83 + 31552643 = 31552726
137 + 31552589 = 31552726
173 + 31552553 = 31552726
239 + 31552487 = 31552726
587 + 31552139 = 31552726
599 + 31552127 = 31552726

Showing the first eight; more decompositions exist.
