Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522598, here are decompositions:

7 + 31522591 = 31522598
139 + 31522459 = 31522598
157 + 31522441 = 31522598
241 + 31522357 = 31522598
271 + 31522327 = 31522598
379 + 31522219 = 31522598
577 + 31522021 = 31522598
607 + 31521991 = 31522598

Showing the first eight; more decompositions exist.
