Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484492, here are decompositions:

31 + 31484461 = 31484492
43 + 31484449 = 31484492
79 + 31484413 = 31484492
139 + 31484353 = 31484492
211 + 31484281 = 31484492
283 + 31484209 = 31484492
313 + 31484179 = 31484492
331 + 31484161 = 31484492

Showing the first eight; more decompositions exist.
