Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547954, here are decompositions:

37 + 31547917 = 31547954
103 + 31547851 = 31547954
223 + 31547731 = 31547954
271 + 31547683 = 31547954
283 + 31547671 = 31547954
313 + 31547641 = 31547954
337 + 31547617 = 31547954
397 + 31547557 = 31547954

Showing the first eight; more decompositions exist.
