Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980138, here are decompositions:

7 + 980131 = 980138
31 + 980107 = 980138
67 + 980071 = 980138
151 + 979987 = 980138
307 + 979831 = 980138
331 + 979807 = 980138
421 + 979717 = 980138
487 + 979651 = 980138

Showing the first eight; more decompositions exist.
