Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541954, here are decompositions:

61 + 31541893 = 31541954
97 + 31541857 = 31541954
127 + 31541827 = 31541954
193 + 31541761 = 31541954
277 + 31541677 = 31541954
373 + 31541581 = 31541954
397 + 31541557 = 31541954
487 + 31541467 = 31541954

Showing the first eight; more decompositions exist.
