Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951780, here are decompositions:

31 + 951749 = 951780
83 + 951697 = 951780
131 + 951649 = 951780
139 + 951641 = 951780
157 + 951623 = 951780
191 + 951589 = 951780
197 + 951583 = 951780
199 + 951581 = 951780

Showing the first eight; more decompositions exist.
