Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532140, here are decompositions:

41 + 532099 = 532140
47 + 532093 = 532140
71 + 532069 = 532140
79 + 532061 = 532140
107 + 532033 = 532140
113 + 532027 = 532140
131 + 532009 = 532140
139 + 532001 = 532140

Showing the first eight; more decompositions exist.
