Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55140, here are decompositions:
- 13 + 55127 = 55140
- 23 + 55117 = 55140
- 31 + 55109 = 55140
- 37 + 55103 = 55140
- 61 + 55079 = 55140
- 67 + 55073 = 55140
- 79 + 55061 = 55140
- 83 + 55057 = 55140
Showing the first eight; more decompositions exist.
