Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532054, here are decompositions:

241 + 31531813 = 31532054
571 + 31531483 = 31532054
601 + 31531453 = 31532054
751 + 31531303 = 31532054
787 + 31531267 = 31532054
937 + 31531117 = 31532054
991 + 31531063 = 31532054
997 + 31531057 = 31532054

Showing the first eight; more decompositions exist.
