Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622450, here are decompositions:

61 + 31622389 = 31622450
73 + 31622377 = 31622450
103 + 31622347 = 31622450
157 + 31622293 = 31622450
163 + 31622287 = 31622450
193 + 31622257 = 31622450
271 + 31622179 = 31622450
283 + 31622167 = 31622450

Showing the first eight; more decompositions exist.
