Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620350, here are decompositions:

7 + 31620343 = 31620350
127 + 31620223 = 31620350
199 + 31620151 = 31620350
211 + 31620139 = 31620350
241 + 31620109 = 31620350
283 + 31620067 = 31620350
313 + 31620037 = 31620350
331 + 31620019 = 31620350

Showing the first eight; more decompositions exist.
