Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462514, here are decompositions:

7 + 31462507 = 31462514
43 + 31462471 = 31462514
73 + 31462441 = 31462514
151 + 31462363 = 31462514
157 + 31462357 = 31462514
163 + 31462351 = 31462514
241 + 31462273 = 31462514
373 + 31462141 = 31462514

Showing the first eight; more decompositions exist.
