Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18588, here are decompositions:
- 5 + 18583 = 18588
- 47 + 18541 = 18588
- 67 + 18521 = 18588
- 71 + 18517 = 18588
- 107 + 18481 = 18588
- 127 + 18461 = 18588
- 131 + 18457 = 18588
- 137 + 18451 = 18588
Showing the first eight; more decompositions exist.
