Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740042, here are decompositions:

5 + 8740037 = 8740042
89 + 8739953 = 8740042
131 + 8739911 = 8740042
173 + 8739869 = 8740042
191 + 8739851 = 8740042
239 + 8739803 = 8740042
293 + 8739749 = 8740042
419 + 8739623 = 8740042

Showing the first eight; more decompositions exist.
