Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91542, here are decompositions:
- 13 + 91529 = 91542
- 29 + 91513 = 91542
- 43 + 91499 = 91542
- 79 + 91463 = 91542
- 83 + 91459 = 91542
- 89 + 91453 = 91542
- 109 + 91433 = 91542
- 131 + 91411 = 91542
Showing the first eight; more decompositions exist.
