Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670242, here are decompositions:

3 + 8670239 = 8670242
211 + 8670031 = 8670242
313 + 8669929 = 8670242
331 + 8669911 = 8670242
349 + 8669893 = 8670242
421 + 8669821 = 8670242
541 + 8669701 = 8670242
571 + 8669671 = 8670242

Showing the first eight; more decompositions exist.
