Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484452, here are decompositions:

3 + 31484449 = 31484452
89 + 31484363 = 31484452
113 + 31484339 = 31484452
149 + 31484303 = 31484452
359 + 31484093 = 31484452
383 + 31484069 = 31484452
563 + 31483889 = 31484452
569 + 31483883 = 31484452

Showing the first eight; more decompositions exist.
