Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460230, here are decompositions:

101 + 31460129 = 31460230
167 + 31460063 = 31460230
281 + 31459949 = 31460230
293 + 31459937 = 31460230
383 + 31459847 = 31460230
401 + 31459829 = 31460230
521 + 31459709 = 31460230
563 + 31459667 = 31460230

Showing the first eight; more decompositions exist.
