Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598508, here are decompositions:

59 + 31598449 = 31598508
89 + 31598419 = 31598508
107 + 31598401 = 31598508
127 + 31598381 = 31598508
131 + 31598377 = 31598508
181 + 31598327 = 31598508
229 + 31598279 = 31598508
241 + 31598267 = 31598508

Showing the first eight; more decompositions exist.
