Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591734, here are decompositions:

11 + 31591723 = 31591734
23 + 31591711 = 31591734
47 + 31591687 = 31591734
67 + 31591667 = 31591734
131 + 31591603 = 31591734
137 + 31591597 = 31591734
157 + 31591577 = 31591734
197 + 31591537 = 31591734

Showing the first eight; more decompositions exist.
