Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461762, here are decompositions:

19 + 31461743 = 31461762
89 + 31461673 = 31461762
109 + 31461653 = 31461762
191 + 31461571 = 31461762
193 + 31461569 = 31461762
229 + 31461533 = 31461762
239 + 31461523 = 31461762
281 + 31461481 = 31461762

Showing the first eight; more decompositions exist.
