Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484500, here are decompositions:

83 + 31484417 = 31484500
137 + 31484363 = 31484500
197 + 31484303 = 31484500
233 + 31484267 = 31484500
263 + 31484237 = 31484500
293 + 31484207 = 31484500
419 + 31484081 = 31484500
431 + 31484069 = 31484500

Showing the first eight; more decompositions exist.
