Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504598, here are decompositions:

7 + 31504591 = 31504598
31 + 31504567 = 31504598
211 + 31504387 = 31504598
241 + 31504357 = 31504598
271 + 31504327 = 31504598
379 + 31504219 = 31504598
397 + 31504201 = 31504598
409 + 31504189 = 31504598

Showing the first eight; more decompositions exist.
