Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544542, here are decompositions:

11 + 31544531 = 31544542
149 + 31544393 = 31544542
179 + 31544363 = 31544542
353 + 31544189 = 31544542
389 + 31544153 = 31544542
443 + 31544099 = 31544542
503 + 31544039 = 31544542
509 + 31544033 = 31544542

Showing the first eight; more decompositions exist.
