Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90442, here are decompositions:

3 + 90439 = 90442
5 + 90437 = 90442
41 + 90401 = 90442
71 + 90371 = 90442
83 + 90359 = 90442
89 + 90353 = 90442
179 + 90263 = 90442
239 + 90203 = 90442

Showing the first eight; more decompositions exist.
