Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75142, here are decompositions:

59 + 75083 = 75142
101 + 75041 = 75142
113 + 75029 = 75142
131 + 75011 = 75142
239 + 74903 = 75142
251 + 74891 = 75142
269 + 74873 = 75142
281 + 74861 = 75142

Showing the first eight; more decompositions exist.
