Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045402, here are decompositions:
- 5 + 1045397 = 1045402
- 11 + 1045391 = 1045402
- 53 + 1045349 = 1045402
- 173 + 1045229 = 1045402
- 179 + 1045223 = 1045402
- 251 + 1045151 = 1045402
- 359 + 1045043 = 1045402
- 389 + 1045013 = 1045402
Showing the first eight; more decompositions exist.
