Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482884, here are decompositions:

61 + 31482823 = 31482884
241 + 31482643 = 31482884
271 + 31482613 = 31482884
373 + 31482511 = 31482884
457 + 31482427 = 31482884
541 + 31482343 = 31482884
547 + 31482337 = 31482884
577 + 31482307 = 31482884

Showing the first eight; more decompositions exist.
