Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71604, here are decompositions:
- 7 + 71597 = 71604
- 11 + 71593 = 71604
- 41 + 71563 = 71604
- 53 + 71551 = 71604
- 67 + 71537 = 71604
- 101 + 71503 = 71604
- 131 + 71473 = 71604
- 151 + 71453 = 71604
Showing the first eight; more decompositions exist.
