Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156804, here are decompositions:

5 + 156799 = 156804
7 + 156797 = 156804
23 + 156781 = 156804
71 + 156733 = 156804
97 + 156707 = 156804
101 + 156703 = 156804
113 + 156691 = 156804
127 + 156677 = 156804

Showing the first eight; more decompositions exist.
