Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173804, here are decompositions:

31 + 173773 = 173804
61 + 173743 = 173804
97 + 173707 = 173804
157 + 173647 = 173804
307 + 173497 = 173804
313 + 173491 = 173804
331 + 173473 = 173804
373 + 173431 = 173804

Showing the first eight; more decompositions exist.
