Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122472, here are decompositions:
- 19 + 122453 = 122472
- 23 + 122449 = 122472
- 29 + 122443 = 122472
- 71 + 122401 = 122472
- 73 + 122399 = 122472
- 79 + 122393 = 122472
- 83 + 122389 = 122472
- 109 + 122363 = 122472
Showing the first eight; more decompositions exist.
