Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70428, here are decompositions:

5 + 70423 = 70428
47 + 70381 = 70428
101 + 70327 = 70428
107 + 70321 = 70428
131 + 70297 = 70428
139 + 70289 = 70428
157 + 70271 = 70428
179 + 70249 = 70428

Showing the first eight; more decompositions exist.
