Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478380, here are decompositions:
- 43 + 33478337 = 33478380
- 73 + 33478307 = 33478380
- 97 + 33478283 = 33478380
- 107 + 33478273 = 33478380
- 149 + 33478231 = 33478380
- 179 + 33478201 = 33478380
- 181 + 33478199 = 33478380
- 191 + 33478189 = 33478380
Showing the first eight; more decompositions exist.
