Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548234, here are decompositions:

101 + 31548133 = 31548234
131 + 31548103 = 31548234
227 + 31548007 = 31548234
241 + 31547993 = 31548234
281 + 31547953 = 31548234
313 + 31547921 = 31548234
317 + 31547917 = 31548234
373 + 31547861 = 31548234

Showing the first eight; more decompositions exist.
