Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2450, here are decompositions:
- 3 + 2447 = 2450
- 13 + 2437 = 2450
- 61 + 2389 = 2450
- 67 + 2383 = 2450
- 73 + 2377 = 2450
- 79 + 2371 = 2450
- 103 + 2347 = 2450
- 109 + 2341 = 2450
Showing the first eight; more decompositions exist.
