Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465138, here are decompositions:

5 + 465133 = 465138
19 + 465119 = 465138
31 + 465107 = 465138
59 + 465079 = 465138
61 + 465077 = 465138
67 + 465071 = 465138
71 + 465067 = 465138
97 + 465041 = 465138

Showing the first eight; more decompositions exist.
