Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045156, here are decompositions:
- 3 + 1045153 = 1045156
- 5 + 1045151 = 1045156
- 113 + 1045043 = 1045156
- 263 + 1044893 = 1045156
- 317 + 1044839 = 1045156
- 347 + 1044809 = 1045156
- 389 + 1044767 = 1045156
- 419 + 1044737 = 1045156
Showing the first eight; more decompositions exist.
