Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506692, here are decompositions:

3 + 31506689 = 31506692
163 + 31506529 = 31506692
181 + 31506511 = 31506692
271 + 31506421 = 31506692
409 + 31506283 = 31506692
421 + 31506271 = 31506692
499 + 31506193 = 31506692
601 + 31506091 = 31506692

Showing the first eight; more decompositions exist.
