Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462546, here are decompositions:

107 + 31462439 = 31462546
113 + 31462433 = 31462546
173 + 31462373 = 31462546
197 + 31462349 = 31462546
233 + 31462313 = 31462546
257 + 31462289 = 31462546
419 + 31462127 = 31462546
443 + 31462103 = 31462546

Showing the first eight; more decompositions exist.
