Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40004, here are decompositions:
- 67 + 39937 = 40004
- 103 + 39901 = 40004
- 127 + 39877 = 40004
- 157 + 39847 = 40004
- 163 + 39841 = 40004
- 271 + 39733 = 40004
- 277 + 39727 = 40004
- 337 + 39667 = 40004
Showing the first eight; more decompositions exist.
