Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450346, here are decompositions:

127 + 31450219 = 31450346
139 + 31450207 = 31450346
229 + 31450117 = 31450346
313 + 31450033 = 31450346
379 + 31449967 = 31450346
409 + 31449937 = 31450346
523 + 31449823 = 31450346
607 + 31449739 = 31450346

Showing the first eight; more decompositions exist.
