Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462304, here are decompositions:

31 + 31462273 = 31462304
37 + 31462267 = 31462304
163 + 31462141 = 31462304
283 + 31462021 = 31462304
463 + 31461841 = 31462304
487 + 31461817 = 31462304
541 + 31461763 = 31462304
607 + 31461697 = 31462304

Showing the first eight; more decompositions exist.
