Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78450, here are decompositions:
- 11 + 78439 = 78450
- 13 + 78437 = 78450
- 23 + 78427 = 78450
- 83 + 78367 = 78450
- 103 + 78347 = 78450
- 109 + 78341 = 78450
- 139 + 78311 = 78450
- 149 + 78301 = 78450
Showing the first eight; more decompositions exist.
