Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627974, here are decompositions:

5 + 31627969 = 31627974
13 + 31627961 = 31627974
43 + 31627931 = 31627974
47 + 31627927 = 31627974
71 + 31627903 = 31627974
113 + 31627861 = 31627974
163 + 31627811 = 31627974
173 + 31627801 = 31627974

Showing the first eight; more decompositions exist.
