Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750740, here are decompositions:

3 + 8750737 = 8750740
83 + 8750657 = 8750740
101 + 8750639 = 8750740
149 + 8750591 = 8750740
191 + 8750549 = 8750740
239 + 8750501 = 8750740
269 + 8750471 = 8750740
293 + 8750447 = 8750740

Showing the first eight; more decompositions exist.
