Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15140, here are decompositions:
- 3 + 15137 = 15140
- 19 + 15121 = 15140
- 67 + 15073 = 15140
- 79 + 15061 = 15140
- 109 + 15031 = 15140
- 127 + 15013 = 15140
- 157 + 14983 = 15140
- 193 + 14947 = 15140
Showing the first eight; more decompositions exist.
