Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154508, here are decompositions:

7 + 154501 = 154508
139 + 154369 = 154508
157 + 154351 = 154508
229 + 154279 = 154508
241 + 154267 = 154508
349 + 154159 = 154508
397 + 154111 = 154508
421 + 154087 = 154508

Showing the first eight; more decompositions exist.
