Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88020, here are decompositions:

13 + 88007 = 88020
17 + 88003 = 88020
19 + 88001 = 88020
29 + 87991 = 88020
43 + 87977 = 88020
47 + 87973 = 88020
59 + 87961 = 88020
61 + 87959 = 88020

Showing the first eight; more decompositions exist.
