Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610876, here are decompositions:

97 + 31610779 = 31610876
103 + 31610773 = 31610876
307 + 31610569 = 31610876
313 + 31610563 = 31610876
337 + 31610539 = 31610876
373 + 31610503 = 31610876
439 + 31610437 = 31610876
463 + 31610413 = 31610876

Showing the first eight; more decompositions exist.
