Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523846, here are decompositions:

7 + 31523839 = 31523846
43 + 31523803 = 31523846
97 + 31523749 = 31523846
139 + 31523707 = 31523846
199 + 31523647 = 31523846
307 + 31523539 = 31523846
373 + 31523473 = 31523846
379 + 31523467 = 31523846

Showing the first eight; more decompositions exist.
