Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130738, here are decompositions:

89 + 130649 = 130738
107 + 130631 = 130738
149 + 130589 = 130738
191 + 130547 = 130738
269 + 130469 = 130738
281 + 130457 = 130738
359 + 130379 = 130738
389 + 130349 = 130738

Showing the first eight; more decompositions exist.
