Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619002, here are decompositions:

3 + 31618999 = 31619002
11 + 31618991 = 31619002
53 + 31618949 = 31619002
59 + 31618943 = 31619002
101 + 31618901 = 31619002
131 + 31618871 = 31619002
179 + 31618823 = 31619002
251 + 31618751 = 31619002

Showing the first eight; more decompositions exist.
