Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547126, here are decompositions:

139 + 31546987 = 31547126
157 + 31546969 = 31547126
283 + 31546843 = 31547126
313 + 31546813 = 31547126
337 + 31546789 = 31547126
367 + 31546759 = 31547126
409 + 31546717 = 31547126
463 + 31546663 = 31547126

Showing the first eight; more decompositions exist.
