Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574552, here are decompositions:

73 + 31574479 = 31574552
103 + 31574449 = 31574552
109 + 31574443 = 31574552
223 + 31574329 = 31574552
349 + 31574203 = 31574552
379 + 31574173 = 31574552
421 + 31574131 = 31574552
733 + 31573819 = 31574552

Showing the first eight; more decompositions exist.
