Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479932, here are decompositions:

103 + 31479829 = 31479932
139 + 31479793 = 31479932
163 + 31479769 = 31479932
193 + 31479739 = 31479932
283 + 31479649 = 31479932
313 + 31479619 = 31479932
373 + 31479559 = 31479932
433 + 31479499 = 31479932

Showing the first eight; more decompositions exist.
