Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141806, here are decompositions:

3 + 141803 = 141806
13 + 141793 = 141806
37 + 141769 = 141806
97 + 141709 = 141806
109 + 141697 = 141806
127 + 141679 = 141806
139 + 141667 = 141806
157 + 141649 = 141806

Showing the first eight; more decompositions exist.
