Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552942, here are decompositions:

23 + 31552919 = 31552942
59 + 31552883 = 31552942
89 + 31552853 = 31552942
233 + 31552709 = 31552942
353 + 31552589 = 31552942
389 + 31552553 = 31552942
521 + 31552421 = 31552942
983 + 31551959 = 31552942

Showing the first eight; more decompositions exist.
