Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484884, here are decompositions:

47 + 31484837 = 31484884
83 + 31484801 = 31484884
107 + 31484777 = 31484884
113 + 31484771 = 31484884
131 + 31484753 = 31484884
173 + 31484711 = 31484884
257 + 31484627 = 31484884
467 + 31484417 = 31484884

Showing the first eight; more decompositions exist.
