Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460338, here are decompositions:

17 + 31460321 = 31460338
47 + 31460291 = 31460338
59 + 31460279 = 31460338
71 + 31460267 = 31460338
389 + 31459949 = 31460338
401 + 31459937 = 31460338
479 + 31459859 = 31460338
491 + 31459847 = 31460338

Showing the first eight; more decompositions exist.
