Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71402, here are decompositions:
- 3 + 71399 = 71402
- 13 + 71389 = 71402
- 43 + 71359 = 71402
- 61 + 71341 = 71402
- 73 + 71329 = 71402
- 109 + 71293 = 71402
- 139 + 71263 = 71402
- 193 + 71209 = 71402
Showing the first eight; more decompositions exist.
