Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484546, here are decompositions:

3 + 31484543 = 31484546
13 + 31484533 = 31484546
43 + 31484503 = 31484546
97 + 31484449 = 31484546
193 + 31484353 = 31484546
229 + 31484317 = 31484546
307 + 31484239 = 31484546
337 + 31484209 = 31484546

Showing the first eight; more decompositions exist.
