Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747140, here are decompositions:

29 + 8747111 = 8747140
47 + 8747093 = 8747140
173 + 8746967 = 8747140
191 + 8746949 = 8747140
293 + 8746847 = 8747140
383 + 8746757 = 8747140
431 + 8746709 = 8747140
443 + 8746697 = 8747140

Showing the first eight; more decompositions exist.
