Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621058, here are decompositions:

31 + 31621027 = 31621058
127 + 31620931 = 31621058
307 + 31620751 = 31621058
349 + 31620709 = 31621058
379 + 31620679 = 31621058
397 + 31620661 = 31621058
457 + 31620601 = 31621058
487 + 31620571 = 31621058

Showing the first eight; more decompositions exist.
