Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53642, here are decompositions:
- 3 + 53639 = 53642
- 13 + 53629 = 53642
- 19 + 53623 = 53642
- 31 + 53611 = 53642
- 73 + 53569 = 53642
- 139 + 53503 = 53642
- 163 + 53479 = 53642
- 223 + 53419 = 53642
Showing the first eight; more decompositions exist.
