Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562950, here are decompositions:

101 + 31562849 = 31562950
149 + 31562801 = 31562950
173 + 31562777 = 31562950
239 + 31562711 = 31562950
347 + 31562603 = 31562950
383 + 31562567 = 31562950
431 + 31562519 = 31562950
449 + 31562501 = 31562950

Showing the first eight; more decompositions exist.
