Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520264, here are decompositions:

31 + 31520233 = 31520264
277 + 31519987 = 31520264
313 + 31519951 = 31520264
331 + 31519933 = 31520264
337 + 31519927 = 31520264
421 + 31519843 = 31520264
463 + 31519801 = 31520264
577 + 31519687 = 31520264

Showing the first eight; more decompositions exist.
