Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707120, here are decompositions:
- 17 + 8707103 = 8707120
- 29 + 8707091 = 8707120
- 83 + 8707037 = 8707120
- 89 + 8707031 = 8707120
- 113 + 8707007 = 8707120
- 137 + 8706983 = 8707120
- 167 + 8706953 = 8707120
- 173 + 8706947 = 8707120
Showing the first eight; more decompositions exist.
