Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25004, here are decompositions:
- 37 + 24967 = 25004
- 61 + 24943 = 25004
- 97 + 24907 = 25004
- 127 + 24877 = 25004
- 157 + 24847 = 25004
- 163 + 24841 = 25004
- 211 + 24793 = 25004
- 223 + 24781 = 25004
Showing the first eight; more decompositions exist.
