Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71804, here are decompositions:
- 43 + 71761 = 71804
- 97 + 71707 = 71804
- 157 + 71647 = 71804
- 211 + 71593 = 71804
- 241 + 71563 = 71804
- 277 + 71527 = 71804
- 331 + 71473 = 71804
- 367 + 71437 = 71804
Showing the first eight; more decompositions exist.
