Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153804, here are decompositions:

41 + 153763 = 153804
47 + 153757 = 153804
61 + 153743 = 153804
71 + 153733 = 153804
103 + 153701 = 153804
163 + 153641 = 153804
181 + 153623 = 153804
193 + 153611 = 153804

Showing the first eight; more decompositions exist.
