Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574174, here are decompositions:

43 + 31574131 = 31574174
67 + 31574107 = 31574174
103 + 31574071 = 31574174
127 + 31574047 = 31574174
421 + 31573753 = 31574174
547 + 31573627 = 31574174
613 + 31573561 = 31574174
661 + 31573513 = 31574174

Showing the first eight; more decompositions exist.
