Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741890, here are decompositions:

23 + 8741867 = 8741890
29 + 8741861 = 8741890
89 + 8741801 = 8741890
137 + 8741753 = 8741890
149 + 8741741 = 8741890
191 + 8741699 = 8741890
251 + 8741639 = 8741890
281 + 8741609 = 8741890

Showing the first eight; more decompositions exist.
