Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496374, here are decompositions:

3 + 31496371 = 31496374
5 + 31496369 = 31496374
53 + 31496321 = 31496374
113 + 31496261 = 31496374
233 + 31496141 = 31496374
251 + 31496123 = 31496374
317 + 31496057 = 31496374
347 + 31496027 = 31496374

Showing the first eight; more decompositions exist.
