Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548742, here are decompositions:

3 + 31548739 = 31548742
83 + 31548659 = 31548742
89 + 31548653 = 31548742
101 + 31548641 = 31548742
149 + 31548593 = 31548742
179 + 31548563 = 31548742
191 + 31548551 = 31548742
311 + 31548431 = 31548742

Showing the first eight; more decompositions exist.
