Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98442, here are decompositions:

13 + 98429 = 98442
23 + 98419 = 98442
31 + 98411 = 98442
53 + 98389 = 98442
73 + 98369 = 98442
173 + 98269 = 98442
191 + 98251 = 98442
229 + 98213 = 98442

Showing the first eight; more decompositions exist.
