Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591846, here are decompositions:

3 + 31591843 = 31591846
53 + 31591793 = 31591846
107 + 31591739 = 31591846
113 + 31591733 = 31591846
179 + 31591667 = 31591846
197 + 31591649 = 31591846
269 + 31591577 = 31591846
347 + 31591499 = 31591846

Showing the first eight; more decompositions exist.
