Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79542, here are decompositions:
- 5 + 79537 = 79542
- 11 + 79531 = 79542
- 61 + 79481 = 79542
- 109 + 79433 = 79542
- 131 + 79411 = 79542
- 149 + 79393 = 79542
- 163 + 79379 = 79542
- 193 + 79349 = 79542
Showing the first eight; more decompositions exist.
