Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122430, here are decompositions:
- 29 + 122401 = 122430
- 31 + 122399 = 122430
- 37 + 122393 = 122430
- 41 + 122389 = 122430
- 43 + 122387 = 122430
- 67 + 122363 = 122430
- 83 + 122347 = 122430
- 103 + 122327 = 122430
Showing the first eight; more decompositions exist.
