Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980438, here are decompositions:

7 + 980431 = 980438
37 + 980401 = 980438
61 + 980377 = 980438
139 + 980299 = 980438
241 + 980197 = 980438
307 + 980131 = 980438
331 + 980107 = 980438
367 + 980071 = 980438

Showing the first eight; more decompositions exist.
