Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73542, here are decompositions:
- 13 + 73529 = 73542
- 19 + 73523 = 73542
- 59 + 73483 = 73542
- 71 + 73471 = 73542
- 83 + 73459 = 73542
- 89 + 73453 = 73542
- 109 + 73433 = 73542
- 163 + 73379 = 73542
Showing the first eight; more decompositions exist.
