Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542450, here are decompositions:

11 + 31542439 = 31542450
13 + 31542437 = 31542450
31 + 31542419 = 31542450
53 + 31542397 = 31542450
59 + 31542391 = 31542450
73 + 31542377 = 31542450
109 + 31542341 = 31542450
127 + 31542323 = 31542450

Showing the first eight; more decompositions exist.
