Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687954, here are decompositions:

31 + 8687923 = 8687954
43 + 8687911 = 8687954
73 + 8687881 = 8687954
127 + 8687827 = 8687954
157 + 8687797 = 8687954
241 + 8687713 = 8687954
283 + 8687671 = 8687954
313 + 8687641 = 8687954

Showing the first eight; more decompositions exist.
