Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591034, here are decompositions:

3 + 31591031 = 31591034
43 + 31590991 = 31591034
103 + 31590931 = 31591034
127 + 31590907 = 31591034
157 + 31590877 = 31591034
193 + 31590841 = 31591034
271 + 31590763 = 31591034
367 + 31590667 = 31591034

Showing the first eight; more decompositions exist.
