Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980540, here are decompositions:

37 + 980503 = 980540
109 + 980431 = 980540
139 + 980401 = 980540
163 + 980377 = 980540
241 + 980299 = 980540
367 + 980173 = 980540
409 + 980131 = 980540
433 + 980107 = 980540

Showing the first eight; more decompositions exist.
