Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460900, here are decompositions:

61 + 31460839 = 31460900
67 + 31460833 = 31460900
109 + 31460791 = 31460900
157 + 31460743 = 31460900
199 + 31460701 = 31460900
223 + 31460677 = 31460900
349 + 31460551 = 31460900
409 + 31460491 = 31460900

Showing the first eight; more decompositions exist.
