Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1058442, here are decompositions:
- 19 + 1058423 = 1058442
- 23 + 1058419 = 1058442
- 53 + 1058389 = 1058442
- 59 + 1058383 = 1058442
- 61 + 1058381 = 1058442
- 89 + 1058353 = 1058442
- 101 + 1058341 = 1058442
- 103 + 1058339 = 1058442
Showing the first eight; more decompositions exist.
