Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051380, here are decompositions:
- 7 + 1051373 = 1051380
- 47 + 1051333 = 1051380
- 61 + 1051319 = 1051380
- 67 + 1051313 = 1051380
- 79 + 1051301 = 1051380
- 89 + 1051291 = 1051380
- 97 + 1051283 = 1051380
- 103 + 1051277 = 1051380
Showing the first eight; more decompositions exist.
