Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142560, here are decompositions:
- 7 + 142553 = 142560
- 13 + 142547 = 142560
- 17 + 142543 = 142560
- 23 + 142537 = 142560
- 31 + 142529 = 142560
- 59 + 142501 = 142560
- 107 + 142453 = 142560
- 127 + 142433 = 142560
Showing the first eight; more decompositions exist.
