Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520348, here are decompositions:

31 + 31520317 = 31520348
229 + 31520119 = 31520348
331 + 31520017 = 31520348
337 + 31520011 = 31520348
397 + 31519951 = 31520348
421 + 31519927 = 31520348
439 + 31519909 = 31520348
547 + 31519801 = 31520348

Showing the first eight; more decompositions exist.
