Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611946, here are decompositions:

5 + 31611941 = 31611946
29 + 31611917 = 31611946
53 + 31611893 = 31611946
227 + 31611719 = 31611946
419 + 31611527 = 31611946
479 + 31611467 = 31611946
617 + 31611329 = 31611946
647 + 31611299 = 31611946

Showing the first eight; more decompositions exist.
