Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756790, here are decompositions:
- 19 + 8756771 = 8756790
- 83 + 8756707 = 8756790
- 101 + 8756689 = 8756790
- 103 + 8756687 = 8756790
- 113 + 8756677 = 8756790
- 131 + 8756659 = 8756790
- 137 + 8756653 = 8756790
- 157 + 8756633 = 8756790
Showing the first eight; more decompositions exist.
