Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522346, here are decompositions:

7 + 31522339 = 31522346
19 + 31522327 = 31522346
103 + 31522243 = 31522346
127 + 31522219 = 31522346
139 + 31522207 = 31522346
367 + 31521979 = 31522346
463 + 31521883 = 31522346
607 + 31521739 = 31522346

Showing the first eight; more decompositions exist.
