Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85442, here are decompositions:

3 + 85439 = 85442
13 + 85429 = 85442
31 + 85411 = 85442
61 + 85381 = 85442
73 + 85369 = 85442
79 + 85363 = 85442
109 + 85333 = 85442
139 + 85303 = 85442

Showing the first eight; more decompositions exist.
