Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591832, here are decompositions:

109 + 31591723 = 31591832
229 + 31591603 = 31591832
379 + 31591453 = 31591832
541 + 31591291 = 31591832
661 + 31591171 = 31591832
673 + 31591159 = 31591832
691 + 31591141 = 31591832
733 + 31591099 = 31591832

Showing the first eight; more decompositions exist.
