Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71422, here are decompositions:
- 3 + 71419 = 71422
- 11 + 71411 = 71422
- 23 + 71399 = 71422
- 59 + 71363 = 71422
- 83 + 71339 = 71422
- 89 + 71333 = 71422
- 173 + 71249 = 71422
- 251 + 71171 = 71422
Showing the first eight; more decompositions exist.
