Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750130, here are decompositions:

7 + 8750123 = 8750130
23 + 8750107 = 8750130
29 + 8750101 = 8750130
61 + 8750069 = 8750130
83 + 8750047 = 8750130
97 + 8750033 = 8750130
113 + 8750017 = 8750130
139 + 8749991 = 8750130

Showing the first eight; more decompositions exist.
