Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610846, here are decompositions:

67 + 31610779 = 31610846
73 + 31610773 = 31610846
139 + 31610707 = 31610846
277 + 31610569 = 31610846
283 + 31610563 = 31610846
307 + 31610539 = 31610846
409 + 31610437 = 31610846
433 + 31610413 = 31610846

Showing the first eight; more decompositions exist.
