Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620692, here are decompositions:

13 + 31620679 = 31620692
31 + 31620661 = 31620692
193 + 31620499 = 31620692
211 + 31620481 = 31620692
283 + 31620409 = 31620692
349 + 31620343 = 31620692
463 + 31620229 = 31620692
541 + 31620151 = 31620692

Showing the first eight; more decompositions exist.
