Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610066, here are decompositions:

3 + 31610063 = 31610066
43 + 31610023 = 31610066
73 + 31609993 = 31610066
109 + 31609957 = 31610066
307 + 31609759 = 31610066
373 + 31609693 = 31610066
457 + 31609609 = 31610066
547 + 31609519 = 31610066

Showing the first eight; more decompositions exist.
