Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478604, here are decompositions:

5 + 31478599 = 31478604
11 + 31478593 = 31478604
23 + 31478581 = 31478604
37 + 31478567 = 31478604
83 + 31478521 = 31478604
193 + 31478411 = 31478604
211 + 31478393 = 31478604
233 + 31478371 = 31478604

Showing the first eight; more decompositions exist.
