Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039680, here are decompositions:
- 13 + 1039667 = 1039680
- 23 + 1039657 = 1039680
- 29 + 1039651 = 1039680
- 73 + 1039607 = 1039680
- 127 + 1039553 = 1039680
- 137 + 1039543 = 1039680
- 163 + 1039517 = 1039680
- 167 + 1039513 = 1039680
Showing the first eight; more decompositions exist.
