Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531834, here are decompositions:

17 + 31531817 = 31531834
83 + 31531751 = 31531834
107 + 31531727 = 31531834
167 + 31531667 = 31531834
311 + 31531523 = 31531834
431 + 31531403 = 31531834
563 + 31531271 = 31531834
617 + 31531217 = 31531834

Showing the first eight; more decompositions exist.
