Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118978, here are decompositions:
- 5 + 118973 = 118978
- 11 + 118967 = 118978
- 47 + 118931 = 118978
- 71 + 118907 = 118978
- 179 + 118799 = 118978
- 191 + 118787 = 118978
- 227 + 118751 = 118978
- 239 + 118739 = 118978
Showing the first eight; more decompositions exist.
