Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462724, here are decompositions:

151 + 31462573 = 31462724
193 + 31462531 = 31462724
283 + 31462441 = 31462724
367 + 31462357 = 31462724
373 + 31462351 = 31462724
457 + 31462267 = 31462724
883 + 31461841 = 31462724
907 + 31461817 = 31462724

Showing the first eight; more decompositions exist.
