Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541426, here are decompositions:

67 + 31541359 = 31541426
79 + 31541347 = 31541426
157 + 31541269 = 31541426
193 + 31541233 = 31541426
313 + 31541113 = 31541426
379 + 31541047 = 31541426
409 + 31541017 = 31541426
487 + 31540939 = 31541426

Showing the first eight; more decompositions exist.
