Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610048, here are decompositions:

37 + 31610011 = 31610048
199 + 31609849 = 31610048
229 + 31609819 = 31610048
271 + 31609777 = 31610048
307 + 31609741 = 31610048
439 + 31609609 = 31610048
487 + 31609561 = 31610048
499 + 31609549 = 31610048

Showing the first eight; more decompositions exist.
