Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750140, here are decompositions:

17 + 8750123 = 8750140
71 + 8750069 = 8750140
101 + 8750039 = 8750140
107 + 8750033 = 8750140
149 + 8749991 = 8750140
293 + 8749847 = 8750140
353 + 8749787 = 8750140
389 + 8749751 = 8750140

Showing the first eight; more decompositions exist.
