Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047542, here are decompositions:
- 3 + 1047539 = 1047542
- 31 + 1047511 = 1047542
- 43 + 1047499 = 1047542
- 73 + 1047469 = 1047542
- 151 + 1047391 = 1047542
- 163 + 1047379 = 1047542
- 229 + 1047313 = 1047542
- 271 + 1047271 = 1047542
Showing the first eight; more decompositions exist.
