Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980842, here are decompositions:

11 + 980831 = 980842
41 + 980801 = 980842
113 + 980729 = 980842
131 + 980711 = 980842
251 + 980591 = 980842
263 + 980579 = 980842
293 + 980549 = 980842
353 + 980489 = 980842

Showing the first eight; more decompositions exist.
