Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620374, here are decompositions:

31 + 31620343 = 31620374
73 + 31620301 = 31620374
151 + 31620223 = 31620374
223 + 31620151 = 31620374
307 + 31620067 = 31620374
337 + 31620037 = 31620374
421 + 31619953 = 31620374
463 + 31619911 = 31620374

Showing the first eight; more decompositions exist.
