Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482584, here are decompositions:

73 + 31482511 = 31482584
157 + 31482427 = 31482584
241 + 31482343 = 31482584
277 + 31482307 = 31482584
307 + 31482277 = 31482584
313 + 31482271 = 31482584
337 + 31482247 = 31482584
487 + 31482097 = 31482584

Showing the first eight; more decompositions exist.
