Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488794, here are decompositions:

61 + 31488733 = 31488794
163 + 31488631 = 31488794
313 + 31488481 = 31488794
331 + 31488463 = 31488794
523 + 31488271 = 31488794
661 + 31488133 = 31488794
853 + 31487941 = 31488794
877 + 31487917 = 31488794

Showing the first eight; more decompositions exist.
