Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515602, here are decompositions:

3 + 31515599 = 31515602
43 + 31515559 = 31515602
331 + 31515271 = 31515602
409 + 31515193 = 31515602
523 + 31515079 = 31515602
691 + 31514911 = 31515602
709 + 31514893 = 31515602
733 + 31514869 = 31515602

Showing the first eight; more decompositions exist.
