Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71802, here are decompositions:

13 + 71789 = 71802
41 + 71761 = 71802
61 + 71741 = 71802
83 + 71719 = 71802
89 + 71713 = 71802
103 + 71699 = 71802
109 + 71693 = 71802
131 + 71671 = 71802

Showing the first eight; more decompositions exist.
