Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742010, here are decompositions:

23 + 8741987 = 8742010
59 + 8741951 = 8742010
149 + 8741861 = 8742010
197 + 8741813 = 8742010
257 + 8741753 = 8742010
269 + 8741741 = 8742010
311 + 8741699 = 8742010
401 + 8741609 = 8742010

Showing the first eight; more decompositions exist.
