Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30442, here are decompositions:

11 + 30431 = 30442
53 + 30389 = 30442
101 + 30341 = 30442
149 + 30293 = 30442
173 + 30269 = 30442
239 + 30203 = 30442
281 + 30161 = 30442
353 + 30089 = 30442

Showing the first eight; more decompositions exist.
