Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951580, here are decompositions:

23 + 951557 = 951580
83 + 951497 = 951580
89 + 951491 = 951580
101 + 951479 = 951580
131 + 951449 = 951580
167 + 951413 = 951580
173 + 951407 = 951580
191 + 951389 = 951580

Showing the first eight; more decompositions exist.
