Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100804, here are decompositions:

3 + 100801 = 100804
5 + 100799 = 100804
17 + 100787 = 100804
71 + 100733 = 100804
101 + 100703 = 100804
131 + 100673 = 100804
191 + 100613 = 100804
257 + 100547 = 100804

Showing the first eight; more decompositions exist.
