Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484974, here are decompositions:

71 + 31484903 = 31484974
137 + 31484837 = 31484974
173 + 31484801 = 31484974
197 + 31484777 = 31484974
233 + 31484741 = 31484974
263 + 31484711 = 31484974
347 + 31484627 = 31484974
431 + 31484543 = 31484974

Showing the first eight; more decompositions exist.
