Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499746, here are decompositions:

347 + 31499399 = 31499746
359 + 31499387 = 31499746
419 + 31499327 = 31499746
449 + 31499297 = 31499746
479 + 31499267 = 31499746
557 + 31499189 = 31499746
563 + 31499183 = 31499746
587 + 31499159 = 31499746

Showing the first eight; more decompositions exist.
