Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90842, here are decompositions:

19 + 90823 = 90842
139 + 90703 = 90842
163 + 90679 = 90842
211 + 90631 = 90842
223 + 90619 = 90842
313 + 90529 = 90842
331 + 90511 = 90842
373 + 90469 = 90842

Showing the first eight; more decompositions exist.
