Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542462, here are decompositions:

5 + 31542457 = 31542462
23 + 31542439 = 31542462
43 + 31542419 = 31542462
71 + 31542391 = 31542462
89 + 31542373 = 31542462
103 + 31542359 = 31542462
139 + 31542323 = 31542462
181 + 31542281 = 31542462

Showing the first eight; more decompositions exist.
