Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100020, here are decompositions:

17 + 100003 = 100020
29 + 99991 = 100020
31 + 99989 = 100020
59 + 99961 = 100020
97 + 99923 = 100020
113 + 99907 = 100020
139 + 99881 = 100020
149 + 99871 = 100020

Showing the first eight; more decompositions exist.
