Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7424, here are decompositions:
- 7 + 7417 = 7424
- 13 + 7411 = 7424
- 31 + 7393 = 7424
- 73 + 7351 = 7424
- 103 + 7321 = 7424
- 127 + 7297 = 7424
- 181 + 7243 = 7424
- 211 + 7213 = 7424
Showing the first eight; more decompositions exist.
