Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544396, here are decompositions:

3 + 31544393 = 31544396
73 + 31544323 = 31544396
229 + 31544167 = 31544396
307 + 31544089 = 31544396
409 + 31543987 = 31544396
523 + 31543873 = 31544396
613 + 31543783 = 31544396
619 + 31543777 = 31544396

Showing the first eight; more decompositions exist.
