Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462544, here are decompositions:

13 + 31462531 = 31462544
37 + 31462507 = 31462544
73 + 31462471 = 31462544
103 + 31462441 = 31462544
163 + 31462381 = 31462544
181 + 31462363 = 31462544
193 + 31462351 = 31462544
271 + 31462273 = 31462544

Showing the first eight; more decompositions exist.
