Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532140, here are decompositions:

23 + 31532117 = 31532140
137 + 31532003 = 31532140
173 + 31531967 = 31532140
257 + 31531883 = 31532140
389 + 31531751 = 31532140
461 + 31531679 = 31532140
491 + 31531649 = 31532140
617 + 31531523 = 31532140

Showing the first eight; more decompositions exist.
