Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90542, here are decompositions:
- 13 + 90529 = 90542
- 19 + 90523 = 90542
- 31 + 90511 = 90542
- 43 + 90499 = 90542
- 61 + 90481 = 90542
- 73 + 90469 = 90542
- 103 + 90439 = 90542
- 139 + 90403 = 90542
Showing the first eight; more decompositions exist.
