Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488344, here are decompositions:

73 + 31488271 = 31488344
211 + 31488133 = 31488344
313 + 31488031 = 31488344
331 + 31488013 = 31488344
367 + 31487977 = 31488344
541 + 31487803 = 31488344
997 + 31487347 = 31488344
1033 + 31487311 = 31488344

Showing the first eight; more decompositions exist.
