Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547282, here are decompositions:

73 + 31547209 = 31547282
79 + 31547203 = 31547282
139 + 31547143 = 31547282
181 + 31547101 = 31547282
313 + 31546969 = 31547282
373 + 31546909 = 31547282
421 + 31546861 = 31547282
439 + 31546843 = 31547282

Showing the first eight; more decompositions exist.
