Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462388, here are decompositions:

7 + 31462381 = 31462388
31 + 31462357 = 31462388
37 + 31462351 = 31462388
367 + 31462021 = 31462388
409 + 31461979 = 31462388
439 + 31461949 = 31462388
547 + 31461841 = 31462388
571 + 31461817 = 31462388

Showing the first eight; more decompositions exist.
