Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719042, here are decompositions:

5 + 8719037 = 8719042
11 + 8719031 = 8719042
89 + 8718953 = 8719042
173 + 8718869 = 8719042
191 + 8718851 = 8719042
239 + 8718803 = 8719042
263 + 8718779 = 8719042
461 + 8718581 = 8719042

Showing the first eight; more decompositions exist.
