Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120778, here are decompositions:
- 11 + 120767 = 120778
- 29 + 120749 = 120778
- 41 + 120737 = 120778
- 89 + 120689 = 120778
- 101 + 120677 = 120778
- 107 + 120671 = 120778
- 131 + 120647 = 120778
- 137 + 120641 = 120778
Showing the first eight; more decompositions exist.
