Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460972, here are decompositions:

43 + 31460929 = 31460972
139 + 31460833 = 31460972
163 + 31460809 = 31460972
181 + 31460791 = 31460972
229 + 31460743 = 31460972
271 + 31460701 = 31460972
421 + 31460551 = 31460972
463 + 31460509 = 31460972

Showing the first eight; more decompositions exist.
