Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519054, here are decompositions:

5 + 31519049 = 31519054
101 + 31518953 = 31519054
131 + 31518923 = 31519054
173 + 31518881 = 31519054
191 + 31518863 = 31519054
227 + 31518827 = 31519054
401 + 31518653 = 31519054
461 + 31518593 = 31519054

Showing the first eight; more decompositions exist.
