Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61404, here are decompositions:
- 23 + 61381 = 61404
- 41 + 61363 = 61404
- 47 + 61357 = 61404
- 61 + 61343 = 61404
- 71 + 61333 = 61404
- 73 + 61331 = 61404
- 107 + 61297 = 61404
- 113 + 61291 = 61404
Showing the first eight; more decompositions exist.
