Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462892, here are decompositions:

3 + 31462889 = 31462892
61 + 31462831 = 31462892
163 + 31462729 = 31462892
283 + 31462609 = 31462892
313 + 31462579 = 31462892
421 + 31462471 = 31462892
541 + 31462351 = 31462892
619 + 31462273 = 31462892

Showing the first eight; more decompositions exist.
