Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611050, here are decompositions:

7 + 31611043 = 31611050
13 + 31611037 = 31611050
139 + 31610911 = 31611050
157 + 31610893 = 31611050
271 + 31610779 = 31611050
277 + 31610773 = 31611050
409 + 31610641 = 31611050
421 + 31610629 = 31611050

Showing the first eight; more decompositions exist.
