Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100480, here are decompositions:

11 + 100469 = 100480
89 + 100391 = 100480
101 + 100379 = 100480
137 + 100343 = 100480
167 + 100313 = 100480
311 + 100169 = 100480
431 + 100049 = 100480
461 + 100019 = 100480

Showing the first eight; more decompositions exist.
