Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552298, here are decompositions:

61 + 31552237 = 31552298
229 + 31552069 = 31552298
241 + 31552057 = 31552298
397 + 31551901 = 31552298
439 + 31551859 = 31552298
541 + 31551757 = 31552298
577 + 31551721 = 31552298
751 + 31551547 = 31552298

Showing the first eight; more decompositions exist.
