Goldbach decomposition

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.
