Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747340, here are decompositions:
- 11 + 8747329 = 8747340
- 13 + 8747327 = 8747340
- 67 + 8747273 = 8747340
- 79 + 8747261 = 8747340
- 83 + 8747257 = 8747340
- 89 + 8747251 = 8747340
- 97 + 8747243 = 8747340
- 127 + 8747213 = 8747340
Showing the first eight; more decompositions exist.
