Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449762, here are decompositions:

5 + 31449757 = 31449762
11 + 31449751 = 31449762
23 + 31449739 = 31449762
61 + 31449701 = 31449762
73 + 31449689 = 31449762
83 + 31449679 = 31449762
89 + 31449673 = 31449762
151 + 31449611 = 31449762

Showing the first eight; more decompositions exist.
