Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544534, here are decompositions:

3 + 31544531 = 31544534
163 + 31544371 = 31544534
211 + 31544323 = 31544534
223 + 31544311 = 31544534
313 + 31544221 = 31544534
367 + 31544167 = 31544534
457 + 31544077 = 31544534
523 + 31544011 = 31544534

Showing the first eight; more decompositions exist.
