Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488606, here are decompositions:

43 + 31488563 = 31488606
59 + 31488547 = 31488606
109 + 31488497 = 31488606
113 + 31488493 = 31488606
137 + 31488469 = 31488606
173 + 31488433 = 31488606
199 + 31488407 = 31488606
277 + 31488329 = 31488606

Showing the first eight; more decompositions exist.
