Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2504, here are decompositions:
- 31 + 2473 = 2504
- 37 + 2467 = 2504
- 67 + 2437 = 2504
- 127 + 2377 = 2504
- 157 + 2347 = 2504
- 163 + 2341 = 2504
- 193 + 2311 = 2504
- 211 + 2293 = 2504
Showing the first eight; more decompositions exist.
