Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541506, here are decompositions:

23 + 31541483 = 31541506
89 + 31541417 = 31541506
107 + 31541399 = 31541506
239 + 31541267 = 31541506
263 + 31541243 = 31541506
389 + 31541117 = 31541506
467 + 31541039 = 31541506
683 + 31540823 = 31541506

Showing the first eight; more decompositions exist.
