Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574426, here are decompositions:

7 + 31574419 = 31574426
97 + 31574329 = 31574426
193 + 31574233 = 31574426
223 + 31574203 = 31574426
379 + 31574047 = 31574426
607 + 31573819 = 31574426
673 + 31573753 = 31574426
787 + 31573639 = 31574426

Showing the first eight; more decompositions exist.
