Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511430, here are decompositions:

13 + 511417 = 511430
43 + 511387 = 511430
79 + 511351 = 511430
97 + 511333 = 511430
103 + 511327 = 511430
151 + 511279 = 511430
193 + 511237 = 511430
229 + 511201 = 511430

Showing the first eight; more decompositions exist.
