Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574054, here are decompositions:

7 + 31574047 = 31574054
13 + 31574041 = 31574054
97 + 31573957 = 31574054
223 + 31573831 = 31574054
307 + 31573747 = 31574054
433 + 31573621 = 31574054
541 + 31573513 = 31574054
661 + 31573393 = 31574054

Showing the first eight; more decompositions exist.
