Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462506, here are decompositions:

67 + 31462439 = 31462506
73 + 31462433 = 31462506
149 + 31462357 = 31462506
157 + 31462349 = 31462506
167 + 31462339 = 31462506
193 + 31462313 = 31462506
233 + 31462273 = 31462506
239 + 31462267 = 31462506

Showing the first eight; more decompositions exist.
