Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462512, here are decompositions:

5 + 31462507 = 31462512
31 + 31462481 = 31462512
41 + 31462471 = 31462512
61 + 31462451 = 31462512
71 + 31462441 = 31462512
73 + 31462439 = 31462512
79 + 31462433 = 31462512
131 + 31462381 = 31462512

Showing the first eight; more decompositions exist.
