Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591606, here are decompositions:

3 + 31591603 = 31591606
5 + 31591601 = 31591606
29 + 31591577 = 31591606
89 + 31591517 = 31591606
107 + 31591499 = 31591606
113 + 31591493 = 31591606
197 + 31591409 = 31591606
239 + 31591367 = 31591606

Showing the first eight; more decompositions exist.
