Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528546, here are decompositions:

47 + 31528499 = 31528546
113 + 31528433 = 31528546
173 + 31528373 = 31528546
197 + 31528349 = 31528546
233 + 31528313 = 31528546
263 + 31528283 = 31528546
317 + 31528229 = 31528546
389 + 31528157 = 31528546

Showing the first eight; more decompositions exist.
