Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524700, here are decompositions:

23 + 31524677 = 31524700
59 + 31524641 = 31524700
113 + 31524587 = 31524700
131 + 31524569 = 31524700
167 + 31524533 = 31524700
191 + 31524509 = 31524700
281 + 31524419 = 31524700
443 + 31524257 = 31524700

Showing the first eight; more decompositions exist.
