Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546558, here are decompositions:

5 + 31546553 = 31546558
89 + 31546469 = 31546558
101 + 31546457 = 31546558
107 + 31546451 = 31546558
137 + 31546421 = 31546558
257 + 31546301 = 31546558
359 + 31546199 = 31546558
599 + 31545959 = 31546558

Showing the first eight; more decompositions exist.
