Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63404, here are decompositions:
- 7 + 63397 = 63404
- 13 + 63391 = 63404
- 37 + 63367 = 63404
- 43 + 63361 = 63404
- 67 + 63337 = 63404
- 73 + 63331 = 63404
- 127 + 63277 = 63404
- 157 + 63247 = 63404
Showing the first eight; more decompositions exist.
