Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484902, here are decompositions:

101 + 31484801 = 31484902
131 + 31484771 = 31484902
149 + 31484753 = 31484902
191 + 31484711 = 31484902
359 + 31484543 = 31484902
389 + 31484513 = 31484902
563 + 31484339 = 31484902
599 + 31484303 = 31484902

Showing the first eight; more decompositions exist.
