Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462410, here are decompositions:

29 + 31462381 = 31462410
37 + 31462373 = 31462410
47 + 31462363 = 31462410
53 + 31462357 = 31462410
59 + 31462351 = 31462410
61 + 31462349 = 31462410
71 + 31462339 = 31462410
97 + 31462313 = 31462410

Showing the first eight; more decompositions exist.
