Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484318, here are decompositions:

37 + 31484281 = 31484318
79 + 31484239 = 31484318
109 + 31484209 = 31484318
139 + 31484179 = 31484318
157 + 31484161 = 31484318
337 + 31483981 = 31484318
457 + 31483861 = 31484318
499 + 31483819 = 31484318

Showing the first eight; more decompositions exist.
