Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548424, here are decompositions:

23 + 31548401 = 31548424
101 + 31548323 = 31548424
137 + 31548287 = 31548424
431 + 31547993 = 31548424
443 + 31547981 = 31548424
491 + 31547933 = 31548424
503 + 31547921 = 31548424
563 + 31547861 = 31548424

Showing the first eight; more decompositions exist.
