Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497548, here are decompositions:

7 + 31497541 = 31497548
79 + 31497469 = 31497548
139 + 31497409 = 31497548
157 + 31497391 = 31497548
211 + 31497337 = 31497548
409 + 31497139 = 31497548
421 + 31497127 = 31497548
541 + 31497007 = 31497548

Showing the first eight; more decompositions exist.
