Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502996, here are decompositions:

3 + 31502993 = 31502996
37 + 31502959 = 31502996
43 + 31502953 = 31502996
73 + 31502923 = 31502996
139 + 31502857 = 31502996
307 + 31502689 = 31502996
337 + 31502659 = 31502996
409 + 31502587 = 31502996

Showing the first eight; more decompositions exist.
