Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71804, here are decompositions:

43 + 71761 = 71804
97 + 71707 = 71804
157 + 71647 = 71804
211 + 71593 = 71804
241 + 71563 = 71804
277 + 71527 = 71804
331 + 71473 = 71804
367 + 71437 = 71804

Showing the first eight; more decompositions exist.
