Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101478, here are decompositions:

11 + 101467 = 101478
29 + 101449 = 101478
59 + 101419 = 101478
67 + 101411 = 101478
79 + 101399 = 101478
101 + 101377 = 101478
131 + 101347 = 101478
137 + 101341 = 101478

Showing the first eight; more decompositions exist.
