Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506632, here are decompositions:

103 + 31506529 = 31506632
109 + 31506523 = 31506632
211 + 31506421 = 31506632
349 + 31506283 = 31506632
439 + 31506193 = 31506632
541 + 31506091 = 31506632
571 + 31506061 = 31506632
601 + 31506031 = 31506632

Showing the first eight; more decompositions exist.
