Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598822, here are decompositions:

43 + 31598779 = 31598822
139 + 31598683 = 31598822
373 + 31598449 = 31598822
421 + 31598401 = 31598822
523 + 31598299 = 31598822
631 + 31598191 = 31598822
643 + 31598179 = 31598822
811 + 31598011 = 31598822

Showing the first eight; more decompositions exist.
