Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511370, here are decompositions:

19 + 511351 = 511370
37 + 511333 = 511370
43 + 511327 = 511370
73 + 511297 = 511370
109 + 511261 = 511370
127 + 511243 = 511370
157 + 511213 = 511370
193 + 511177 = 511370

Showing the first eight; more decompositions exist.
