Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7542, here are decompositions:
- 5 + 7537 = 7542
- 13 + 7529 = 7542
- 19 + 7523 = 7542
- 43 + 7499 = 7542
- 53 + 7489 = 7542
- 61 + 7481 = 7542
- 83 + 7459 = 7542
- 109 + 7433 = 7542
Showing the first eight; more decompositions exist.
