Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547060, here are decompositions:

73 + 31546987 = 31547060
79 + 31546981 = 31547060
151 + 31546909 = 31547060
199 + 31546861 = 31547060
229 + 31546831 = 31547060
271 + 31546789 = 31547060
397 + 31546663 = 31547060
439 + 31546621 = 31547060

Showing the first eight; more decompositions exist.
