Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42002, here are decompositions:

3 + 41999 = 42002
19 + 41983 = 42002
43 + 41959 = 42002
61 + 41941 = 42002
109 + 41893 = 42002
139 + 41863 = 42002
151 + 41851 = 42002
193 + 41809 = 42002

Showing the first eight; more decompositions exist.
