Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460500, here are decompositions:

3 + 31460497 = 31460500
17 + 31460483 = 31460500
59 + 31460441 = 31460500
101 + 31460399 = 31460500
131 + 31460369 = 31460500
179 + 31460321 = 31460500
233 + 31460267 = 31460500
563 + 31459937 = 31460500

Showing the first eight; more decompositions exist.
