Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506478, here are decompositions:

17 + 506461 = 506478
19 + 506459 = 506478
29 + 506449 = 506478
61 + 506417 = 506478
97 + 506381 = 506478
127 + 506351 = 506478
131 + 506347 = 506478
139 + 506339 = 506478

Showing the first eight; more decompositions exist.
