Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547276, here are decompositions:

67 + 31547209 = 31547276
73 + 31547203 = 31547276
199 + 31547077 = 31547276
307 + 31546969 = 31547276
367 + 31546909 = 31547276
433 + 31546843 = 31547276
463 + 31546813 = 31547276
487 + 31546789 = 31547276

Showing the first eight; more decompositions exist.
