Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574216, here are decompositions:

13 + 31574203 = 31574216
43 + 31574173 = 31574216
109 + 31574107 = 31574216
397 + 31573819 = 31574216
463 + 31573753 = 31574216
577 + 31573639 = 31574216
823 + 31573393 = 31574216
853 + 31573363 = 31574216

Showing the first eight; more decompositions exist.
