Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77242, here are decompositions:
- 3 + 77239 = 77242
- 5 + 77237 = 77242
- 29 + 77213 = 77242
- 41 + 77201 = 77242
- 71 + 77171 = 77242
- 89 + 77153 = 77242
- 101 + 77141 = 77242
- 149 + 77093 = 77242
Showing the first eight; more decompositions exist.
