Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547392, here are decompositions:

53 + 31547339 = 31547392
89 + 31547303 = 31547392
131 + 31547261 = 31547392
263 + 31547129 = 31547392
353 + 31547039 = 31547392
389 + 31547003 = 31547392
479 + 31546913 = 31547392
593 + 31546799 = 31547392

Showing the first eight; more decompositions exist.
