Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606760, here are decompositions:

7 + 31606753 = 31606760
19 + 31606741 = 31606760
79 + 31606681 = 31606760
103 + 31606657 = 31606760
109 + 31606651 = 31606760
181 + 31606579 = 31606760
223 + 31606537 = 31606760
331 + 31606429 = 31606760

Showing the first eight; more decompositions exist.
