Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574360, here are decompositions:

31 + 31574329 = 31574360
127 + 31574233 = 31574360
157 + 31574203 = 31574360
229 + 31574131 = 31574360
313 + 31574047 = 31574360
541 + 31573819 = 31574360
607 + 31573753 = 31574360
613 + 31573747 = 31574360

Showing the first eight; more decompositions exist.
