Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120648, here are decompositions:
- 7 + 120641 = 120648
- 29 + 120619 = 120648
- 41 + 120607 = 120648
- 61 + 120587 = 120648
- 71 + 120577 = 120648
- 79 + 120569 = 120648
- 97 + 120551 = 120648
- 109 + 120539 = 120648
Showing the first eight; more decompositions exist.
