Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548232, here are decompositions:

83 + 31548149 = 31548232
239 + 31547993 = 31548232
251 + 31547981 = 31548232
311 + 31547921 = 31548232
383 + 31547849 = 31548232
449 + 31547783 = 31548232
641 + 31547591 = 31548232
701 + 31547531 = 31548232

Showing the first eight; more decompositions exist.
