Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576994, here are decompositions:

3 + 31576991 = 31576994
37 + 31576957 = 31576994
103 + 31576891 = 31576994
151 + 31576843 = 31576994
313 + 31576681 = 31576994
541 + 31576453 = 31576994
577 + 31576417 = 31576994
643 + 31576351 = 31576994

Showing the first eight; more decompositions exist.
