Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482802, here are decompositions:

3 + 31482799 = 31482802
23 + 31482779 = 31482802
41 + 31482761 = 31482802
59 + 31482743 = 31482802
233 + 31482569 = 31482802
251 + 31482551 = 31482802
293 + 31482509 = 31482802
401 + 31482401 = 31482802

Showing the first eight; more decompositions exist.
