Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541548, here are decompositions:

41 + 31541507 = 31541548
131 + 31541417 = 31541548
149 + 31541399 = 31541548
251 + 31541297 = 31541548
281 + 31541267 = 31541548
419 + 31541129 = 31541548
431 + 31541117 = 31541548
509 + 31541039 = 31541548

Showing the first eight; more decompositions exist.
