Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71654, here are decompositions:
- 7 + 71647 = 71654
- 61 + 71593 = 71654
- 103 + 71551 = 71654
- 127 + 71527 = 71654
- 151 + 71503 = 71654
- 181 + 71473 = 71654
- 211 + 71443 = 71654
- 241 + 71413 = 71654
Showing the first eight; more decompositions exist.
