Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610960, here are decompositions:

67 + 31610893 = 31610960
181 + 31610779 = 31610960
331 + 31610629 = 31610960
373 + 31610587 = 31610960
379 + 31610581 = 31610960
397 + 31610563 = 31610960
421 + 31610539 = 31610960
439 + 31610521 = 31610960

Showing the first eight; more decompositions exist.
