Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597338, here are decompositions:

107 + 31597231 = 31597338
139 + 31597199 = 31597338
211 + 31597127 = 31597338
239 + 31597099 = 31597338
257 + 31597081 = 31597338
307 + 31597031 = 31597338
347 + 31596991 = 31597338
389 + 31596949 = 31597338

Showing the first eight; more decompositions exist.
