Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451332, here are decompositions:

71 + 31451261 = 31451332
113 + 31451219 = 31451332
131 + 31451201 = 31451332
173 + 31451159 = 31451332
383 + 31450949 = 31451332
491 + 31450841 = 31451332
503 + 31450829 = 31451332
509 + 31450823 = 31451332

Showing the first eight; more decompositions exist.
