Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552858, here are decompositions:

5 + 31552853 = 31552858
11 + 31552847 = 31552858
41 + 31552817 = 31552858
131 + 31552727 = 31552858
137 + 31552721 = 31552858
149 + 31552709 = 31552858
269 + 31552589 = 31552858
587 + 31552271 = 31552858

Showing the first eight; more decompositions exist.
