Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482932, here are decompositions:

43 + 31482889 = 31482932
73 + 31482859 = 31482932
109 + 31482823 = 31482932
223 + 31482709 = 31482932
373 + 31482559 = 31482932
421 + 31482511 = 31482932
433 + 31482499 = 31482932
661 + 31482271 = 31482932

Showing the first eight; more decompositions exist.
