Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461876, here are decompositions:

53 + 31461823 = 31461876
59 + 31461817 = 31461876
97 + 31461779 = 31461876
113 + 31461763 = 31461876
139 + 31461737 = 31461876
179 + 31461697 = 31461876
223 + 31461653 = 31461876
307 + 31461569 = 31461876

Showing the first eight; more decompositions exist.
