Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115578, here are decompositions:

7 + 115571 = 115578
17 + 115561 = 115578
31 + 115547 = 115578
79 + 115499 = 115578
107 + 115471 = 115578
109 + 115469 = 115578
149 + 115429 = 115578
157 + 115421 = 115578

Showing the first eight; more decompositions exist.
