Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86138, here are decompositions:

7 + 86131 = 86138
61 + 86077 = 86138
109 + 86029 = 86138
127 + 86011 = 86138
139 + 85999 = 86138
229 + 85909 = 86138
307 + 85831 = 86138
421 + 85717 = 86138

Showing the first eight; more decompositions exist.
