Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461232, here are decompositions:

3 + 31461229 = 31461232
41 + 31461191 = 31461232
53 + 31461179 = 31461232
59 + 31461173 = 31461232
71 + 31461161 = 31461232
83 + 31461149 = 31461232
281 + 31460951 = 31461232
353 + 31460879 = 31461232

Showing the first eight; more decompositions exist.
