Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541728, here are decompositions:

131 + 31541597 = 31541728
137 + 31541591 = 31541728
311 + 31541417 = 31541728
431 + 31541297 = 31541728
461 + 31541267 = 31541728
587 + 31541141 = 31541728
599 + 31541129 = 31541728
677 + 31541051 = 31541728

Showing the first eight; more decompositions exist.
