Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547062, here are decompositions:

23 + 31547039 = 31547062
59 + 31547003 = 31547062
149 + 31546913 = 31547062
263 + 31546799 = 31547062
353 + 31546709 = 31547062
401 + 31546661 = 31547062
461 + 31546601 = 31547062
479 + 31546583 = 31547062

Showing the first eight; more decompositions exist.
