Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121396, here are decompositions:
- 17 + 121379 = 121396
- 29 + 121367 = 121396
- 47 + 121349 = 121396
- 53 + 121343 = 121396
- 83 + 121313 = 121396
- 113 + 121283 = 121396
- 137 + 121259 = 121396
- 167 + 121229 = 121396
Showing the first eight; more decompositions exist.
