Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62642, here are decompositions:
- 3 + 62639 = 62642
- 61 + 62581 = 62642
- 79 + 62563 = 62642
- 103 + 62539 = 62642
- 109 + 62533 = 62642
- 241 + 62401 = 62642
- 331 + 62311 = 62642
- 409 + 62233 = 62642
Showing the first eight; more decompositions exist.
