Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520294, here are decompositions:

61 + 31520233 = 31520294
277 + 31520017 = 31520294
283 + 31520011 = 31520294
307 + 31519987 = 31520294
367 + 31519927 = 31520294
457 + 31519837 = 31520294
541 + 31519753 = 31520294
607 + 31519687 = 31520294

Showing the first eight; more decompositions exist.
