Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40802, here are decompositions:

31 + 40771 = 40802
43 + 40759 = 40802
103 + 40699 = 40802
109 + 40693 = 40802
163 + 40639 = 40802
193 + 40609 = 40802
211 + 40591 = 40802
271 + 40531 = 40802

Showing the first eight; more decompositions exist.
