Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51604, here are decompositions:
- 5 + 51599 = 51604
- 11 + 51593 = 51604
- 23 + 51581 = 51604
- 41 + 51563 = 51604
- 53 + 51551 = 51604
- 83 + 51521 = 51604
- 101 + 51503 = 51604
- 131 + 51473 = 51604
Showing the first eight; more decompositions exist.
