Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473452, here are decompositions:

139 + 31473313 = 31473452
211 + 31473241 = 31473452
421 + 31473031 = 31473452
523 + 31472929 = 31473452
601 + 31472851 = 31473452
613 + 31472839 = 31473452
1093 + 31472359 = 31473452
1213 + 31472239 = 31473452

Showing the first eight; more decompositions exist.
