Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523380, here are decompositions:
- 23 + 523357 = 523380
- 29 + 523351 = 523380
- 31 + 523349 = 523380
- 47 + 523333 = 523380
- 73 + 523307 = 523380
- 83 + 523297 = 523380
- 167 + 523213 = 523380
- 173 + 523207 = 523380
Showing the first eight; more decompositions exist.
