Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993480, here are decompositions:
- 13 + 993467 = 993480
- 29 + 993451 = 993480
- 43 + 993437 = 993480
- 73 + 993407 = 993480
- 79 + 993401 = 993480
- 83 + 993397 = 993480
- 113 + 993367 = 993480
- 139 + 993341 = 993480
Showing the first eight; more decompositions exist.
