Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522396, here are decompositions:

23 + 31522373 = 31522396
83 + 31522313 = 31522396
149 + 31522247 = 31522396
167 + 31522229 = 31522396
293 + 31522103 = 31522396
383 + 31522013 = 31522396
419 + 31521977 = 31522396
443 + 31521953 = 31522396

Showing the first eight; more decompositions exist.
