Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591036, here are decompositions:

5 + 31591031 = 31591036
23 + 31591013 = 31591036
107 + 31590929 = 31591036
137 + 31590899 = 31591036
149 + 31590887 = 31591036
233 + 31590803 = 31591036
353 + 31590683 = 31591036
419 + 31590617 = 31591036

Showing the first eight; more decompositions exist.
