Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544362, here are decompositions:

149 + 31544213 = 31544362
173 + 31544189 = 31544362
191 + 31544171 = 31544362
263 + 31544099 = 31544362
383 + 31543979 = 31544362
401 + 31543961 = 31544362
449 + 31543913 = 31544362
491 + 31543871 = 31544362

Showing the first eight; more decompositions exist.
