Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620134, here are decompositions:

3 + 31620131 = 31620134
67 + 31620067 = 31620134
97 + 31620037 = 31620134
181 + 31619953 = 31620134
223 + 31619911 = 31620134
313 + 31619821 = 31620134
373 + 31619761 = 31620134
421 + 31619713 = 31620134

Showing the first eight; more decompositions exist.
