Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522850, here are decompositions:

3 + 31522847 = 31522850
103 + 31522747 = 31522850
157 + 31522693 = 31522850
181 + 31522669 = 31522850
193 + 31522657 = 31522850
409 + 31522441 = 31522850
439 + 31522411 = 31522850
487 + 31522363 = 31522850

Showing the first eight; more decompositions exist.
