Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90138, here are decompositions:
- 11 + 90127 = 90138
- 17 + 90121 = 90138
- 31 + 90107 = 90138
- 67 + 90071 = 90138
- 71 + 90067 = 90138
- 79 + 90059 = 90138
- 107 + 90031 = 90138
- 127 + 90011 = 90138
Showing the first eight; more decompositions exist.
