Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611876, here are decompositions:

7 + 31611869 = 31611876
47 + 31611829 = 31611876
59 + 31611817 = 31611876
73 + 31611803 = 31611876
139 + 31611737 = 31611876
157 + 31611719 = 31611876
167 + 31611709 = 31611876
173 + 31611703 = 31611876

Showing the first eight; more decompositions exist.
