Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045458, here are decompositions:
- 31 + 1045427 = 1045458
- 47 + 1045411 = 1045458
- 61 + 1045397 = 1045458
- 67 + 1045391 = 1045458
- 109 + 1045349 = 1045458
- 137 + 1045321 = 1045458
- 149 + 1045309 = 1045458
- 151 + 1045307 = 1045458
Showing the first eight; more decompositions exist.
