Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591414, here are decompositions:

5 + 31591409 = 31591414
47 + 31591367 = 31591414
83 + 31591331 = 31591414
227 + 31591187 = 31591414
347 + 31591067 = 31591414
353 + 31591061 = 31591414
383 + 31591031 = 31591414
401 + 31591013 = 31591414

Showing the first eight; more decompositions exist.
