Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476750, here are decompositions:

7 + 31476743 = 31476750
17 + 31476733 = 31476750
23 + 31476727 = 31476750
47 + 31476703 = 31476750
59 + 31476691 = 31476750
127 + 31476623 = 31476750
139 + 31476611 = 31476750
157 + 31476593 = 31476750

Showing the first eight; more decompositions exist.
