Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53140, here are decompositions:
- 11 + 53129 = 53140
- 23 + 53117 = 53140
- 47 + 53093 = 53140
- 53 + 53087 = 53140
- 71 + 53069 = 53140
- 89 + 53051 = 53140
- 137 + 53003 = 53140
- 167 + 52973 = 53140
Showing the first eight; more decompositions exist.
