Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523054, here are decompositions:

67 + 31522987 = 31523054
103 + 31522951 = 31523054
181 + 31522873 = 31523054
307 + 31522747 = 31523054
337 + 31522717 = 31523054
397 + 31522657 = 31523054
421 + 31522633 = 31523054
457 + 31522597 = 31523054

Showing the first eight; more decompositions exist.
