Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561706, here are decompositions:

13 + 31561693 = 31561706
37 + 31561669 = 31561706
109 + 31561597 = 31561706
157 + 31561549 = 31561706
277 + 31561429 = 31561706
283 + 31561423 = 31561706
433 + 31561273 = 31561706
607 + 31561099 = 31561706

Showing the first eight; more decompositions exist.
