Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153770, here are decompositions:

7 + 153763 = 153770
13 + 153757 = 153770
31 + 153739 = 153770
37 + 153733 = 153770
163 + 153607 = 153770
181 + 153589 = 153770
241 + 153529 = 153770
271 + 153499 = 153770

Showing the first eight; more decompositions exist.
