Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476542, here are decompositions:

43 + 31476499 = 31476542
109 + 31476433 = 31476542
151 + 31476391 = 31476542
193 + 31476349 = 31476542
199 + 31476343 = 31476542
373 + 31476169 = 31476542
613 + 31475929 = 31476542
631 + 31475911 = 31476542

Showing the first eight; more decompositions exist.
