Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462474, here are decompositions:

3 + 31462471 = 31462474
23 + 31462451 = 31462474
41 + 31462433 = 31462474
101 + 31462373 = 31462474
257 + 31462217 = 31462474
347 + 31462127 = 31462474
467 + 31462007 = 31462474
587 + 31461887 = 31462474

Showing the first eight; more decompositions exist.
