Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85472, here are decompositions:

3 + 85469 = 85472
19 + 85453 = 85472
43 + 85429 = 85472
61 + 85411 = 85472
103 + 85369 = 85472
109 + 85363 = 85472
139 + 85333 = 85472
229 + 85243 = 85472

Showing the first eight; more decompositions exist.
