Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71770, here are decompositions:

29 + 71741 = 71770
59 + 71711 = 71770
71 + 71699 = 71770
107 + 71663 = 71770
137 + 71633 = 71770
173 + 71597 = 71770
233 + 71537 = 71770
317 + 71453 = 71770

Showing the first eight; more decompositions exist.
