Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591674, here are decompositions:

7 + 31591667 = 31591674
71 + 31591603 = 31591674
73 + 31591601 = 31591674
97 + 31591577 = 31591674
137 + 31591537 = 31591674
157 + 31591517 = 31591674
181 + 31591493 = 31591674
197 + 31591477 = 31591674

Showing the first eight; more decompositions exist.
