Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750120, here are decompositions:

13 + 8750107 = 8750120
19 + 8750101 = 8750120
73 + 8750047 = 8750120
103 + 8750017 = 8750120
109 + 8750011 = 8750120
139 + 8749981 = 8750120
193 + 8749927 = 8750120
199 + 8749921 = 8750120

Showing the first eight; more decompositions exist.
