Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750988, here are decompositions:
- 19 + 8750969 = 8750988
- 31 + 8750957 = 8750988
- 41 + 8750947 = 8750988
- 47 + 8750941 = 8750988
- 67 + 8750921 = 8750988
- 97 + 8750891 = 8750988
- 107 + 8750881 = 8750988
- 131 + 8750857 = 8750988
Showing the first eight; more decompositions exist.
