Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541242, here are decompositions:

101 + 31541141 = 31541242
113 + 31541129 = 31541242
191 + 31541051 = 31541242
251 + 31540991 = 31541242
263 + 31540979 = 31541242
281 + 31540961 = 31541242
419 + 31540823 = 31541242
563 + 31540679 = 31541242

Showing the first eight; more decompositions exist.
