Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484892, here are decompositions:

29 + 31484863 = 31484892
53 + 31484839 = 31484892
71 + 31484821 = 31484892
139 + 31484753 = 31484892
151 + 31484741 = 31484892
181 + 31484711 = 31484892
193 + 31484699 = 31484892
349 + 31484543 = 31484892

Showing the first eight; more decompositions exist.
