Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462424, here are decompositions:

43 + 31462381 = 31462424
61 + 31462363 = 31462424
67 + 31462357 = 31462424
73 + 31462351 = 31462424
151 + 31462273 = 31462424
157 + 31462267 = 31462424
283 + 31462141 = 31462424
421 + 31462003 = 31462424

Showing the first eight; more decompositions exist.
