Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610894, here are decompositions:

103 + 31610791 = 31610894
307 + 31610587 = 31610894
313 + 31610581 = 31610894
331 + 31610563 = 31610894
373 + 31610521 = 31610894
457 + 31610437 = 31610894
541 + 31610353 = 31610894
577 + 31610317 = 31610894

Showing the first eight; more decompositions exist.
