Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548004, here are decompositions:

11 + 31547993 = 31548004
23 + 31547981 = 31548004
71 + 31547933 = 31548004
83 + 31547921 = 31548004
167 + 31547837 = 31548004
311 + 31547693 = 31548004
563 + 31547441 = 31548004
647 + 31547357 = 31548004

Showing the first eight; more decompositions exist.
