Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620434, here are decompositions:

3 + 31620431 = 31620434
37 + 31620397 = 31620434
211 + 31620223 = 31620434
283 + 31620151 = 31620434
367 + 31620067 = 31620434
397 + 31620037 = 31620434
421 + 31620013 = 31620434
523 + 31619911 = 31620434

Showing the first eight; more decompositions exist.
