Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541626, here are decompositions:

29 + 31541597 = 31541626
197 + 31541429 = 31541626
227 + 31541399 = 31541626
359 + 31541267 = 31541626
383 + 31541243 = 31541626
509 + 31541117 = 31541626
587 + 31541039 = 31541626
647 + 31540979 = 31541626

Showing the first eight; more decompositions exist.
