Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544744, here are decompositions:

31 + 31544713 = 31544744
157 + 31544587 = 31544744
193 + 31544551 = 31544744
211 + 31544533 = 31544744
373 + 31544371 = 31544744
397 + 31544347 = 31544744
421 + 31544323 = 31544744
433 + 31544311 = 31544744

Showing the first eight; more decompositions exist.
