Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87558, here are decompositions:
- 5 + 87553 = 87558
- 11 + 87547 = 87558
- 17 + 87541 = 87558
- 19 + 87539 = 87558
- 41 + 87517 = 87558
- 47 + 87511 = 87558
- 67 + 87491 = 87558
- 131 + 87427 = 87558
Showing the first eight; more decompositions exist.
