Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71624, here are decompositions:
- 31 + 71593 = 71624
- 61 + 71563 = 71624
- 73 + 71551 = 71624
- 97 + 71527 = 71624
- 151 + 71473 = 71624
- 181 + 71443 = 71624
- 211 + 71413 = 71624
- 271 + 71353 = 71624
Showing the first eight; more decompositions exist.
