Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75090, here are decompositions:

7 + 75083 = 75090
11 + 75079 = 75090
53 + 75037 = 75090
61 + 75029 = 75090
73 + 75017 = 75090
79 + 75011 = 75090
131 + 74959 = 75090
149 + 74941 = 75090

Showing the first eight; more decompositions exist.
