Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5642, here are decompositions:
- 3 + 5639 = 5642
- 19 + 5623 = 5642
- 61 + 5581 = 5642
- 73 + 5569 = 5642
- 79 + 5563 = 5642
- 139 + 5503 = 5642
- 163 + 5479 = 5642
- 193 + 5449 = 5642
Showing the first eight; more decompositions exist.
