Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7284, here are decompositions:
- 31 + 7253 = 7284
- 37 + 7247 = 7284
- 41 + 7243 = 7284
- 47 + 7237 = 7284
- 71 + 7213 = 7284
- 73 + 7211 = 7284
- 97 + 7187 = 7284
- 107 + 7177 = 7284
Showing the first eight; more decompositions exist.
