Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541346, here are decompositions:

79 + 31541267 = 31541346
103 + 31541243 = 31541346
113 + 31541233 = 31541346
167 + 31541179 = 31541346
173 + 31541173 = 31541346
229 + 31541117 = 31541346
233 + 31541113 = 31541346
307 + 31541039 = 31541346

Showing the first eight; more decompositions exist.
