Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591462, here are decompositions:

41 + 31591421 = 31591462
53 + 31591409 = 31591462
113 + 31591349 = 31591462
131 + 31591331 = 31591462
263 + 31591199 = 31591462
401 + 31591061 = 31591462
431 + 31591031 = 31591462
449 + 31591013 = 31591462

Showing the first eight; more decompositions exist.
