Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750144, here are decompositions:

37 + 8750107 = 8750144
43 + 8750101 = 8750144
97 + 8750047 = 8750144
127 + 8750017 = 8750144
163 + 8749981 = 8750144
223 + 8749921 = 8750144
241 + 8749903 = 8750144
307 + 8749837 = 8750144

Showing the first eight; more decompositions exist.
