Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552396, here are decompositions:

3 + 31552393 = 31552396
167 + 31552229 = 31552396
257 + 31552139 = 31552396
269 + 31552127 = 31552396
347 + 31552049 = 31552396
419 + 31551977 = 31552396
569 + 31551827 = 31552396
593 + 31551803 = 31552396

Showing the first eight; more decompositions exist.
