Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751242, here are decompositions:

61 + 8751181 = 8751242
103 + 8751139 = 8751242
151 + 8751091 = 8751242
163 + 8751079 = 8751242
229 + 8751013 = 8751242
349 + 8750893 = 8751242
433 + 8750809 = 8751242
523 + 8750719 = 8751242

Showing the first eight; more decompositions exist.
