Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541798, here are decompositions:

37 + 31541761 = 31541798
61 + 31541737 = 31541798
139 + 31541659 = 31541798
229 + 31541569 = 31541798
241 + 31541557 = 31541798
271 + 31541527 = 31541798
331 + 31541467 = 31541798
349 + 31541449 = 31541798

Showing the first eight; more decompositions exist.
