Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122532, here are decompositions:
- 5 + 122527 = 122532
- 23 + 122509 = 122532
- 29 + 122503 = 122532
- 31 + 122501 = 122532
- 43 + 122489 = 122532
- 61 + 122471 = 122532
- 79 + 122453 = 122532
- 83 + 122449 = 122532
Showing the first eight; more decompositions exist.
