Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700842, here are decompositions:

43 + 8700799 = 8700842
193 + 8700649 = 8700842
313 + 8700529 = 8700842
331 + 8700511 = 8700842
421 + 8700421 = 8700842
673 + 8700169 = 8700842
811 + 8700031 = 8700842
823 + 8700019 = 8700842

Showing the first eight; more decompositions exist.
