Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85430, here are decompositions:

3 + 85427 = 85430
19 + 85411 = 85430
61 + 85369 = 85430
67 + 85363 = 85430
97 + 85333 = 85430
127 + 85303 = 85430
193 + 85237 = 85430
229 + 85201 = 85430

Showing the first eight; more decompositions exist.
