Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7188, here are decompositions:
- 11 + 7177 = 7188
- 29 + 7159 = 7188
- 37 + 7151 = 7188
- 59 + 7129 = 7188
- 61 + 7127 = 7188
- 67 + 7121 = 7188
- 79 + 7109 = 7188
- 109 + 7079 = 7188
Showing the first eight; more decompositions exist.
