Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610834, here are decompositions:

43 + 31610791 = 31610834
61 + 31610773 = 31610834
127 + 31610707 = 31610834
193 + 31610641 = 31610834
271 + 31610563 = 31610834
313 + 31610521 = 31610834
331 + 31610503 = 31610834
397 + 31610437 = 31610834

Showing the first eight; more decompositions exist.
