Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008672, here are decompositions:
- 13 + 1008659 = 1008672
- 59 + 1008613 = 1008672
- 61 + 1008611 = 1008672
- 83 + 1008589 = 1008672
- 101 + 1008571 = 1008672
- 109 + 1008563 = 1008672
- 131 + 1008541 = 1008672
- 173 + 1008499 = 1008672
Showing the first eight; more decompositions exist.
