Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45140, here are decompositions:

3 + 45137 = 45140
13 + 45127 = 45140
19 + 45121 = 45140
79 + 45061 = 45140
127 + 45013 = 45140
157 + 44983 = 45140
181 + 44959 = 45140
223 + 44917 = 45140

Showing the first eight; more decompositions exist.
