Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980402, here are decompositions:

103 + 980299 = 980402
109 + 980293 = 980402
223 + 980179 = 980402
229 + 980173 = 980402
271 + 980131 = 980402
331 + 980071 = 980402
433 + 979969 = 980402
571 + 979831 = 980402

Showing the first eight; more decompositions exist.
