Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544036, here are decompositions:

3 + 31544033 = 31544036
109 + 31543927 = 31544036
163 + 31543873 = 31544036
193 + 31543843 = 31544036
313 + 31543723 = 31544036
367 + 31543669 = 31544036
457 + 31543579 = 31544036
547 + 31543489 = 31544036

Showing the first eight; more decompositions exist.
