Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482488, here are decompositions:

61 + 31482427 = 31482488
139 + 31482349 = 31482488
151 + 31482337 = 31482488
181 + 31482307 = 31482488
211 + 31482277 = 31482488
241 + 31482247 = 31482488
421 + 31482067 = 31482488
577 + 31481911 = 31482488

Showing the first eight; more decompositions exist.
