Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484620, here are decompositions:

3 + 31484617 = 31484620
107 + 31484513 = 31484620
257 + 31484363 = 31484620
281 + 31484339 = 31484620
317 + 31484303 = 31484620
353 + 31484267 = 31484620
383 + 31484237 = 31484620
443 + 31484177 = 31484620

Showing the first eight; more decompositions exist.
