Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532066, here are decompositions:

3 + 31532063 = 31532066
157 + 31531909 = 31532066
439 + 31531627 = 31532066
487 + 31531579 = 31532066
613 + 31531453 = 31532066
967 + 31531099 = 31532066
997 + 31531069 = 31532066
1009 + 31531057 = 31532066

Showing the first eight; more decompositions exist.
