Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42458, here are decompositions:
- 7 + 42451 = 42458
- 61 + 42397 = 42458
- 67 + 42391 = 42458
- 79 + 42379 = 42458
- 109 + 42349 = 42458
- 127 + 42331 = 42458
- 151 + 42307 = 42458
- 271 + 42187 = 42458
Showing the first eight; more decompositions exist.
