Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541452, here are decompositions:

3 + 31541449 = 31541452
23 + 31541429 = 31541452
53 + 31541399 = 31541452
311 + 31541141 = 31541452
401 + 31541051 = 31541452
431 + 31541021 = 31541452
461 + 31540991 = 31541452
491 + 31540961 = 31541452

Showing the first eight; more decompositions exist.
