Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541498, here are decompositions:

31 + 31541467 = 31541498
61 + 31541437 = 31541498
97 + 31541401 = 31541498
139 + 31541359 = 31541498
151 + 31541347 = 31541498
229 + 31541269 = 31541498
337 + 31541161 = 31541498
397 + 31541101 = 31541498

Showing the first eight; more decompositions exist.
