Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71190, here are decompositions:
- 19 + 71171 = 71190
- 23 + 71167 = 71190
- 29 + 71161 = 71190
- 37 + 71153 = 71190
- 43 + 71147 = 71190
- 47 + 71143 = 71190
- 61 + 71129 = 71190
- 71 + 71119 = 71190
Showing the first eight; more decompositions exist.
