Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79242, here are decompositions:
- 11 + 79231 = 79242
- 13 + 79229 = 79242
- 41 + 79201 = 79242
- 61 + 79181 = 79242
- 83 + 79159 = 79242
- 89 + 79153 = 79242
- 103 + 79139 = 79242
- 109 + 79133 = 79242
Showing the first eight; more decompositions exist.
