Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598420, here are decompositions:

3 + 31598417 = 31598420
19 + 31598401 = 31598420
43 + 31598377 = 31598420
67 + 31598353 = 31598420
181 + 31598239 = 31598420
193 + 31598227 = 31598420
229 + 31598191 = 31598420
241 + 31598179 = 31598420

Showing the first eight; more decompositions exist.
