Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473632, here are decompositions:

103 + 31473529 = 31473632
109 + 31473523 = 31473632
349 + 31473283 = 31473632
523 + 31473109 = 31473632
571 + 31473061 = 31473632
601 + 31473031 = 31473632
859 + 31472773 = 31473632
1021 + 31472611 = 31473632

Showing the first eight; more decompositions exist.
