Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742004, here are decompositions:

17 + 8741987 = 8742004
53 + 8741951 = 8742004
71 + 8741933 = 8742004
137 + 8741867 = 8742004
191 + 8741813 = 8742004
251 + 8741753 = 8742004
263 + 8741741 = 8742004
317 + 8741687 = 8742004

Showing the first eight; more decompositions exist.
