Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492184, here are decompositions:

103 + 31492081 = 31492184
151 + 31492033 = 31492184
271 + 31491913 = 31492184
397 + 31491787 = 31492184
457 + 31491727 = 31492184
487 + 31491697 = 31492184
523 + 31491661 = 31492184
547 + 31491637 = 31492184

Showing the first eight; more decompositions exist.
