Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147492, here are decompositions:

5 + 147487 = 147492
11 + 147481 = 147492
41 + 147451 = 147492
43 + 147449 = 147492
73 + 147419 = 147492
83 + 147409 = 147492
101 + 147391 = 147492
139 + 147353 = 147492

Showing the first eight; more decompositions exist.
