Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501138, here are decompositions:

5 + 501133 = 501138
7 + 501131 = 501138
17 + 501121 = 501138
61 + 501077 = 501138
101 + 501037 = 501138
107 + 501031 = 501138
109 + 501029 = 501138
137 + 501001 = 501138

Showing the first eight; more decompositions exist.
