Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70778, here are decompositions:

61 + 70717 = 70778
139 + 70639 = 70778
151 + 70627 = 70778
157 + 70621 = 70778
229 + 70549 = 70778
241 + 70537 = 70778
271 + 70507 = 70778
277 + 70501 = 70778

Showing the first eight; more decompositions exist.
