Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591702, here are decompositions:

53 + 31591649 = 31591702
101 + 31591601 = 31591702
281 + 31591421 = 31591702
293 + 31591409 = 31591702
353 + 31591349 = 31591702
503 + 31591199 = 31591702
641 + 31591061 = 31591702
743 + 31590959 = 31591702

Showing the first eight; more decompositions exist.
