Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462444, here are decompositions:

3 + 31462441 = 31462444
5 + 31462439 = 31462444
11 + 31462433 = 31462444
71 + 31462373 = 31462444
131 + 31462313 = 31462444
227 + 31462217 = 31462444
311 + 31462133 = 31462444
317 + 31462127 = 31462444

Showing the first eight; more decompositions exist.
