Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11578, here are decompositions:
- 29 + 11549 = 11578
- 59 + 11519 = 11578
- 89 + 11489 = 11578
- 107 + 11471 = 11578
- 131 + 11447 = 11578
- 167 + 11411 = 11578
- 179 + 11399 = 11578
- 227 + 11351 = 11578
Showing the first eight; more decompositions exist.
