Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71966, here are decompositions:
- 3 + 71963 = 71966
- 19 + 71947 = 71966
- 67 + 71899 = 71966
- 79 + 71887 = 71966
- 157 + 71809 = 71966
- 373 + 71593 = 71966
- 397 + 71569 = 71966
- 439 + 71527 = 71966
Showing the first eight; more decompositions exist.
