Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731042, here are decompositions:

3 + 8731039 = 8731042
11 + 8731031 = 8731042
59 + 8730983 = 8731042
113 + 8730929 = 8731042
149 + 8730893 = 8731042
179 + 8730863 = 8731042
191 + 8730851 = 8731042
239 + 8730803 = 8731042

Showing the first eight; more decompositions exist.
