Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731832, here are decompositions:

13 + 8731819 = 8731832
223 + 8731609 = 8731832
331 + 8731501 = 8731832
463 + 8731369 = 8731832
523 + 8731309 = 8731832
601 + 8731231 = 8731832
619 + 8731213 = 8731832
631 + 8731201 = 8731832

Showing the first eight; more decompositions exist.
