Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455596, here are decompositions:

97 + 31455499 = 31455596
163 + 31455433 = 31455596
199 + 31455397 = 31455596
229 + 31455367 = 31455596
283 + 31455313 = 31455596
373 + 31455223 = 31455596
457 + 31455139 = 31455596
643 + 31454953 = 31455596

Showing the first eight; more decompositions exist.
