Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588822, here are decompositions:

113 + 31588709 = 31588822
149 + 31588673 = 31588822
179 + 31588643 = 31588822
191 + 31588631 = 31588822
359 + 31588463 = 31588822
383 + 31588439 = 31588822
491 + 31588331 = 31588822
509 + 31588313 = 31588822

Showing the first eight; more decompositions exist.
