Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532254, here are decompositions:

113 + 31532141 = 31532254
137 + 31532117 = 31532254
191 + 31532063 = 31532254
233 + 31532021 = 31532254
251 + 31532003 = 31532254
503 + 31531751 = 31532254
587 + 31531667 = 31532254
797 + 31531457 = 31532254

Showing the first eight; more decompositions exist.
