Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71838, here are decompositions:

17 + 71821 = 71838
29 + 71809 = 71838
31 + 71807 = 71838
61 + 71777 = 71838
97 + 71741 = 71838
127 + 71711 = 71838
131 + 71707 = 71838
139 + 71699 = 71838

Showing the first eight; more decompositions exist.
