Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051542, here are decompositions:
- 43 + 1051499 = 1051542
- 61 + 1051481 = 1051542
- 71 + 1051471 = 1051542
- 73 + 1051469 = 1051542
- 83 + 1051459 = 1051542
- 223 + 1051319 = 1051542
- 229 + 1051313 = 1051542
- 241 + 1051301 = 1051542
Showing the first eight; more decompositions exist.
