Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511354, here are decompositions:

13 + 31511341 = 31511354
67 + 31511287 = 31511354
73 + 31511281 = 31511354
211 + 31511143 = 31511354
283 + 31511071 = 31511354
313 + 31511041 = 31511354
397 + 31510957 = 31511354
421 + 31510933 = 31511354

Showing the first eight; more decompositions exist.
