Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460236, here are decompositions:

107 + 31460129 = 31460236
173 + 31460063 = 31460236
383 + 31459853 = 31460236
389 + 31459847 = 31460236
503 + 31459733 = 31460236
557 + 31459679 = 31460236
569 + 31459667 = 31460236
617 + 31459619 = 31460236

Showing the first eight; more decompositions exist.
