Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747906, here are decompositions:

3 + 8747903 = 8747906
43 + 8747863 = 8747906
103 + 8747803 = 8747906
163 + 8747743 = 8747906
229 + 8747677 = 8747906
283 + 8747623 = 8747906
367 + 8747539 = 8747906
379 + 8747527 = 8747906

Showing the first eight; more decompositions exist.
