Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544942, here are decompositions:

19 + 31544923 = 31544942
43 + 31544899 = 31544942
193 + 31544749 = 31544942
223 + 31544719 = 31544942
229 + 31544713 = 31544942
409 + 31544533 = 31544942
433 + 31544509 = 31544942
571 + 31544371 = 31544942

Showing the first eight; more decompositions exist.
