Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122568, here are decompositions:
- 7 + 122561 = 122568
- 11 + 122557 = 122568
- 41 + 122527 = 122568
- 59 + 122509 = 122568
- 67 + 122501 = 122568
- 71 + 122497 = 122568
- 79 + 122489 = 122568
- 97 + 122471 = 122568
Showing the first eight; more decompositions exist.
