Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7402, here are decompositions:
- 53 + 7349 = 7402
- 71 + 7331 = 7402
- 149 + 7253 = 7402
- 173 + 7229 = 7402
- 191 + 7211 = 7402
- 251 + 7151 = 7402
- 281 + 7121 = 7402
- 293 + 7109 = 7402
Showing the first eight; more decompositions exist.
