Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979880, here are decompositions:
- 7 + 979873 = 979880
- 61 + 979819 = 979880
- 73 + 979807 = 979880
- 163 + 979717 = 979880
- 229 + 979651 = 979880
- 313 + 979567 = 979880
- 331 + 979549 = 979880
- 337 + 979543 = 979880
Showing the first eight; more decompositions exist.
