Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460384, here are decompositions:

37 + 31460347 = 31460384
103 + 31460281 = 31460384
211 + 31460173 = 31460384
331 + 31460053 = 31460384
367 + 31460017 = 31460384
421 + 31459963 = 31460384
577 + 31459807 = 31460384
661 + 31459723 = 31460384

Showing the first eight; more decompositions exist.
