Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552558, here are decompositions:

5 + 31552553 = 31552558
71 + 31552487 = 31552558
137 + 31552421 = 31552558
347 + 31552211 = 31552558
419 + 31552139 = 31552558
431 + 31552127 = 31552558
509 + 31552049 = 31552558
599 + 31551959 = 31552558

Showing the first eight; more decompositions exist.
