Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541746, here are decompositions:

53 + 31541693 = 31541746
113 + 31541633 = 31541746
149 + 31541597 = 31541746
239 + 31541507 = 31541746
263 + 31541483 = 31541746
317 + 31541429 = 31541746
347 + 31541399 = 31541746
449 + 31541297 = 31541746

Showing the first eight; more decompositions exist.
