Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541534, here are decompositions:

7 + 31541527 = 31541534
67 + 31541467 = 31541534
97 + 31541437 = 31541534
373 + 31541161 = 31541534
421 + 31541113 = 31541534
433 + 31541101 = 31541534
463 + 31541071 = 31541534
487 + 31541047 = 31541534

Showing the first eight; more decompositions exist.
