Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591706, here are decompositions:

19 + 31591687 = 31591706
103 + 31591603 = 31591706
109 + 31591597 = 31591706
193 + 31591513 = 31591706
229 + 31591477 = 31591706
457 + 31591249 = 31591706
499 + 31591207 = 31591706
547 + 31591159 = 31591706

Showing the first eight; more decompositions exist.
