Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731282, here are decompositions:

5 + 8731277 = 8731282
71 + 8731211 = 8731282
173 + 8731109 = 8731282
179 + 8731103 = 8731282
251 + 8731031 = 8731282
353 + 8730929 = 8731282
389 + 8730893 = 8731282
401 + 8730881 = 8731282

Showing the first eight; more decompositions exist.
