Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548604, here are decompositions:

11 + 31548593 = 31548604
41 + 31548563 = 31548604
53 + 31548551 = 31548604
71 + 31548533 = 31548604
83 + 31548521 = 31548604
137 + 31548467 = 31548604
173 + 31548431 = 31548604
281 + 31548323 = 31548604

Showing the first eight; more decompositions exist.
