Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021372, here are decompositions:
- 3 + 1021369 = 1021372
- 5 + 1021367 = 1021372
- 41 + 1021331 = 1021372
- 71 + 1021301 = 1021372
- 83 + 1021289 = 1021372
- 89 + 1021283 = 1021372
- 101 + 1021271 = 1021372
- 113 + 1021259 = 1021372
Showing the first eight; more decompositions exist.
