Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5140, here are decompositions:

41 + 5099 = 5140
53 + 5087 = 5140
59 + 5081 = 5140
89 + 5051 = 5140
101 + 5039 = 5140
131 + 5009 = 5140
137 + 5003 = 5140
167 + 4973 = 5140

Showing the first eight; more decompositions exist.
