Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478598, here are decompositions:

5 + 31478593 = 31478598
17 + 31478581 = 31478598
31 + 31478567 = 31478598
127 + 31478471 = 31478598
197 + 31478401 = 31478598
199 + 31478399 = 31478598
227 + 31478371 = 31478598
257 + 31478341 = 31478598

Showing the first eight; more decompositions exist.
