Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72304, here are decompositions:
- 17 + 72287 = 72304
- 53 + 72251 = 72304
- 83 + 72221 = 72304
- 131 + 72173 = 72304
- 137 + 72167 = 72304
- 227 + 72077 = 72304
- 251 + 72053 = 72304
- 257 + 72047 = 72304
Showing the first eight; more decompositions exist.
