Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610936, here are decompositions:

43 + 31610893 = 31610936
157 + 31610779 = 31610936
163 + 31610773 = 31610936
229 + 31610707 = 31610936
307 + 31610629 = 31610936
349 + 31610587 = 31610936
367 + 31610569 = 31610936
373 + 31610563 = 31610936

Showing the first eight; more decompositions exist.
