Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597412, here are decompositions:

151 + 31597261 = 31597412
181 + 31597231 = 31597412
199 + 31597213 = 31597412
283 + 31597129 = 31597412
313 + 31597099 = 31597412
331 + 31597081 = 31597412
409 + 31597003 = 31597412
421 + 31596991 = 31597412

Showing the first eight; more decompositions exist.
