Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511846, here are decompositions:

43 + 31511803 = 31511846
73 + 31511773 = 31511846
103 + 31511743 = 31511846
193 + 31511653 = 31511846
277 + 31511569 = 31511846
307 + 31511539 = 31511846
313 + 31511533 = 31511846
409 + 31511437 = 31511846

Showing the first eight; more decompositions exist.
